I'm using Eclipse, and at random times, it will just freeze up and stop responding. Does this happen to anyone else? It usually happens when I click on a line of code, whether it be Java or XML. Any ideas on how to fix it?
System Specs:
Open your workspace\.metadata\.log file. That will tell you usually what is going wrong.
Try this, it worked for me!
If you happen to have Eclipse not responding anymore sometimes, the reason could be that you sit on a 64bit machine where eclipse needs more memory. Be sure to have (at least) the following configurations in your eclipse.ini (I even use bigger values for the PermSizes):
-Xms512m
-Xmx1024m
-XX:PermSize=64m
-XX:MaxPermSize=128m
I just restarted the adb (Android Debug Bridge) this way:
adb kill-server
adb start-server
and it works again!
Last night at 2am I closed my Eclipse (Juno) just fine. This morning I open it up and I get nothing but "Not Responding" on my 64bit Windows 7 machine.
I looked in [workspace]\.metadata\.log and it showed an error with Invalid property category path: ValidationPropertiesPage
I cuss it out pretty good and then show it who's the boss :
delete [workspace]\.metadata folder
delete [workspace]\[project]\.settings
Open up Eclipse to the same workspace as before, re-import your
project.
Which brings me to another topic... Eclipse -> import -> Android -> Existing Android code into workspace... seems to be broken once again. But that's a different topic.
Very likely your filesystem is out of sync with your Eclipse... Resource is out of sync with the file system. Using SVN? If you "Refresh" all of your projects in explorer, speed returns to normal.
I had similar symptoms recently. Turned out it was caused by the Subversion server being unavailable - once that was restarted I was able to right-click. My environment was Eclipse Luna with Subclipse.
So worth checking that any connected source control systems are operational. Hope that helps.
for me, it was because of all the outgoing files, i.e workspace is not in sync with SVN, due to the 'target' folders (maven project, or when building web project), add them to svn:ignore.
I kept running into this problem every time I tried opening eclipse. I resolved it by unplugging my android device's USB from my laptop, and eclipse worked again.
If there is a project you earlier imported externally (outside of Workspace), that may cause this problem. If you can access Eclipse try to remove it. If you are getting the 'No responding at startup', then go delete the file at source.
This will solve the problem.
I had a problem like you. But I am Windows 8.1 64 bit user. At first I use eclipse Kepler on my 8.1. The eclipse often become not responding when I worked on. After that, I decide to back to eclipse Juno and it works fine now.
This may help
In your eclipse,
1) Go to Help
2) Click Eclipse marketplace
3) search - optimizer
install "optimizer for eclipse"

I recently installed GGTS. It's been good so far but it's starting to annoy me how the dashboard (window) keeps showing up on start up. I checked the preferences but there's nothing there that switches it off. I attempted to uninstall the feature, but the GGTS won't allow me.
You are probably running into this bug: STS-3935. The dashboard is supposed to stay closed when you close it, but in some situations in STS 3.6.2 it doesn't.
If you upgrade to a newer version of STS the problem should go away. If you do not want to upgrade your STS, you can also try running with JDK 8 (so you'll get the new dashboard which is not subject to the bug).
Or, another workaround suggested in the bug-report is to open manually edit the preferences file at workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.springsource.ide.eclipse.dashboard.ui.prefs and add or change the line:
org.springsource.ide.eclipse.dashboard.uidashboard.startup=false

At present I cannot run it (SQL Developer 4.1) because it hangs on "Restoring Editors" while starting. I suppose I've done it by exiting it before by killing sql developer process because it was hanged on fetching objects to Schema Browser so long...
Maybe I would clean some temporary files but can't find any.
Any ideas?
Deleting files from c:\Users\MY_USER\AppData\Roaming\SQL Developer\SQL History
and c:\Users\MY_USER\AppData\Roaming\SQL Developer\System...
Really helped me to resolve the connection issues
Basing on this thread https://community.oracle.com/thread/2564842 I've created own solution.
Extract installation of current version SQL Developer (4.1.0.17.29)
At "c:\Users\MY_USER\AppData\Roaming\SQL Developer\"
I've changed directory name system4.1.0.17.29 to system4.1.0.17.28.
After running newly extracted SQL Developer (4.1.0.17.29) I was prompted to let copy configuration from version 4.1.0.17.28 to 4.1.0.17.29 ;)
Everything works great now. I suppose that running the same (broken) installation after decreasing version could also help.
Remove folders c:\Users\USERNAME\AppData\Roaming\SQL Developer\system4.1.3.20.78\system_cache*. SQLDeveloper will recreate it after launching.
Just execute sqldeveloper as administrator. It works fine!
In my case the problem was because of windows compatibility issue. So I've selected my windows version and it's stop from randomly crash after startup
Our setup:
Windows 10
Sqldeveloper Versions <= 20.4.0
We observed this problem as well. Even worse while working over a VPN connection. I followed a couple of hints with more or less no effect.
To move
C:\Users\<USER>\AppData\Roaming\SQL Developer
to a local directory by adding this line
AddVMOption -Dide.user.dir=c:\temp\sqldev-conf
in the \sqldeveloper\bin\sqldeveloper.conf file gave us some improvement, but the “IndexPreferencesTask” still got stuck several times on startup.
After some more hours on unsuccessful research, we moved back from JDK 11 to JDK 8.
This solved 99% of the problem. The “IndexPreferencesTask” still hangs on startup but for less than a second.
Sounds to me like a problem with JDK 11.
In my case when i changed Tools --> Preferences --> Environment -> Look and Feel to Windows it is solved.
Delete the History files from C:\Users\User\AppData\Roaming\sqldeveloper
Restart the PC
In my case, the solution was kind of weird. After battling to resolve this for 2 days, no luck. Suddenly, on my mac, I searched for sql developer, not sqldeveloper. It popped up a sqldeveloper application (not sure how that is different from what I have been trying to open ), clicked it and boom, it opened. My guess is that there is a copy of that app on my system that I should have been opening rather than trying to open the reinstalled app. Note: I reinstalled the app after it started misbehaving though.
Operating System: Windows 10
Oracle Sqldeveloper Ver: 17.4.0
The problem has been noticed sometime when any network security
patch was installed on your machine. Looks like the patch impacts
your cached data under your user profile folder.
As above Lakh, rtbf and others answered. Removing below folders
will resolve the issue.
C:\Users\<userId>\AppData\Roaming\SQL Developer\SqlHistory
C:\Users\<userId>\AppData\Roaming\SQL Developer\system17.4.0.355.2349
If any one find more approriate reason please feel free to

My Netbeans has been insanely fast for over 2 years, until this morning. Something strange, however, is now happening. Every time i press "copy and paste" ... so CTRL-C, it goes slow. This is what I see:
So, the moment I press CTRL-C, that shows in the bottom, my entire machines goes into super slow mode, and then 5 seconds later it stops.
I've considered maybe there's a keylogger on my machine, but can't find anything. And it's only slow when I copy and paste from Netbeans, nothing else. Maybe Netbeans is sending data out some other way?
Any ideas why Netbeans would just go slow like this?
UPDATE
I only have one project open
I've disabled the git and subversion plugins
I am working on a Laravel project
It's slow when I copy from a VIEW or when I copy from a CONTROLLER (I know css files often go a bit slow because of Parsing, so I figured mentioning this is probably worthwhile)
I followed the advice at the end of this article: here and uninstalled "BlueStacks". Problem solved.
UPDATE
Just in case the article gets deleted, here is the advice the user gives on that page:
I meet the same problem. When I copy a word in the IDE, the IDE does not response until 2 or 3 seconds. I did not confront this problem until few days ago. I try to use the latest netbeans and the latest jdk, but that does not work. Then I find someone said http://bugs.java.com/bugdatabase/view_bug.do?bug_id=5078787 is the problem. And the problem is somewhat about the COM in windows. So I try to install the netbeans to another Win7 PC, and the problem is gone. In that case, I guess the problem is not the netbeans, but some other application in windows. Later I uninstall some of the application I just installed few days ago. And the IDE works right now. The applications I uninstalled is "imc studio" "imc license manager" and "blueStacks" an android simulator. I guess these application may have influence to the COM of Win7. Hope my solution will help to this bug.
You can also just stop the BlueStacks Agent process from Task Manager while you're using NetBeans.
First of all this question has been asked at least twice.
I tried several approaches with no effect.
Here's the problem:
When I try to download/update plugins like EclEmma, Eclipse starts to communicate with the repository and that takes about 5 minutes. After that I get an error:
"An error occured while collecting items to be installed
session context was:(...)
Unable to read repository at http: (...)
Read time out
(... for every *.jar)"
What I was trying to fix the problem was running eclipse as an admin (got vista x86 running) and changing the connection properties from native to direct and back. I also tried deleting saved repositories and adding again. No effect at all.
I have no proxy configured and don't need one.
This is getting kind of personal between me and my IDE :D
So I hope you guys can help me out.
Thanks Zoltán (köszi :D), but i found the error last night.
Resolution
After hours of debugging I figured out that AVG Anti-Virus Software blocks the request. After deactivating it for temporarily, Eclipse installed the new software.
In my case timeout was caused by definition of SOCKS proxy... we have proxy.company.com:80 and I incorrectly provided that proxy to all three (HTTP, HTTPS and SOCKS) connection schemas. Removal of proxy from SOCKS resolved the problem
Try to open the internal web browser of Eclipse (Window menu/Show view/Other...), and navigate to the 1) update site url, and 2) to any webpage.
If the latter one is not working, then Eclipse does not have connection to the internet, and you should try to open a new workspace, and try installing from there (possibly something wrong in the workspace settings).
If the second one works, but the first one does not, that suggests that the update site is not working. In this case report to the developers.
I also had this problem (my system: Win7, jdk7, Eclipse Indigo).
I installed jre6, changed my JAVA_HOME, ran eclipse with the following:
eclipse -debug -consolelog -vm 'c:\Program Files\Java\jre6\bin\java.exe'
Install the plugins/updates, then switch back to using jdk7.
Worked for me!
Temporarily disabling AVG firewall fixed the issue for me.
Eclipse then installed the Android plugin.
In my case, adding these lines to eclipse.ini solved the problem
-vmargs (this one was alreayd there)
-Djava.net.preferIPv4Stack=true

I had exactly the same problem. I did not restart my machine, and just used "eclipse -clean" to start eclipse. It worked. Thanks Jon for the hint.
Does restarting your computer resolve the problem with being able to open the workspace? There is a forum post (http://forums.sun.com/thread.jspa?messageID=3131484#3131484) that describes a similar problem with an identical stack trace as the one shown above. In the post, the author mentions that their machine was low on resources (they did not specify what type of resources were running low).
If restarting your computer does not work, you may want to try starting eclipse with the clean option:
eclipse -clean
The clean option will clean out any caches that Eclipse has created.
If all else fails, you may want to open a bug for this problem at https://bugs.eclipse.org/bugs/. Including a copy of your workspace (if possible), and including the stack trace in the bug would be helpful information for the person trying to diagnose the problem.
Good Luck!
Well, some things you can try are:
Delete workspace .metadata dir. Obviously you will lose your workbench configuration.
Rename your .metadata dir. Start Eclipse, and you will have a new .metadata dir. Close Eclipse, delete the new dir, and rename back the original dir. It sometimes works.
HI,
Check the task manager, whether any java process(java.exe or javaw.exe) running even after the closing of workbench. Kill those processes. You will get this error resolved
For me, I think this has something to do with my dual monitor setup and Actual Multiple Monitors that I have installed. I disabled that and the problem is gone.
This worked when I moved the eclipse.ini from the eclipse install folder (where .exe is present). I ran into this problem when I was trying to increase the heap size in the eclipse.ini file (although I had seen this error earlier)
