I am trying to run Eclipse Galileo, but having following error message on screen:
I have installed jdk-6u21-windows-x64 and also added the environment variables in the PATH. I am running Windows 7 64-bit.
If you're going to use a 64-bit JDK, you should probably get the 64-bit Eclipse instead. They really should match.

I installed a fresh Ubuntu 16.04 VM, Oracle JDK 7, and downloaded the latest Eclipse. But I am getting this error when I try to start Eclipse:
Unrecognized VM option 'UseStringDeduplication'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.
Why am I getting this error on a fresh install? And is it a bad idea to remove that VM option?
Latest version of Eclipse (Neon) requires Java 8 runtime, and the Eclipse website obnoxiously neglects to mention it anywhere from the homepage to the download link for Eclipse, not even a version warning at runtime for Eclipse.
Same error for me in Kubuntu 14.04, eclipse Neon,
I Removed -XX:+UseStringDeduplication from .ini file, it works for me
I know, i'm little to late to the party. I got this issue lately on my Mac. I updated my eclipse (from Mars to Oxygen) all of the sudden i couldn't start my old project. First i thought, this must have something to do with the new eclipse, which wasn't all wrong. Because eclipse.ini file of Oxygen expected java-1.8.
I updated my java to latest (jdk1.8.0_152.jdk), but the problem remained, than i removed these parameters from the eclipse.ini, still was the same, i checked the "Run Configurations" and basically removed the same parameters from the arguments list. Now my projects seem to work just fine. I also needed to restore the platform, since Oxygen use e.4-platform.
Remove these parameters from eclipse.ini file
Select the project and go to "Run As"->"Run Configurations..."-> "Arguments" check the old configurations under "VM arguments" (it can be a product in case of an RCP-project)
removed the VM-option(s)(actually, they can be more) not recognized and "Apply"-> "Run".
I got the same error when I have installed Java 8 and Java 9 in my Ubuntu 16.04. My eclipse version was Neon. As https://wiki.eclipse.org/Eclipse/Installation#Eclipse_4.6_.28Neon.29 describes to start specific eclipse ide you need relevant JDK. For neon, it was Java 8. Since I installed Java 9 using apt-get it was the default JDK. so I have to change the default JDK to Java 8.
You can check which java version used in system-wide with
java -version
`If you want to see which are the versions of JDK installed in Ubuntu then run below command in shell.
sudo update-java-alternatives --list
Then choose which version you want to set. After that run below command.
sudo update-java-alternatives --set [JDK/JRE name e.g. java-8-oracle]
Now run again Eclipse. if the version was the reason to conflict, it will run now. Referred by http://menukanows.com/how-to-set-a-default-jdk-version-in-ubuntu/
String Deduplication – A new feature in Java 8 Update 20
It means you should nt java 1.8 updated later or equal 20.
I faced the same issue on Eclipse Oxygen in Ubuntu.
Tried:
Checking java version (It was already at 1.8.0 so according to the accepted answer, it should work.)
Removing -XX:+UseStringDeduplication from .ini file
Still didn't solve the problem. Then I saw #simgineer's comment:
In my case this was for eclipse oxygen. I had an older version of java
8 installed (jdk1.8.0_05) when I upgraded to the latest (jdk1.8.0_151)
and updated my eclipse.ini to point to the latest as well (since it is
recorded in there during installation) eclipse oxygen started working.
Solution:
Updated JDK from 1.8.0 to jdk1.8.0_231 and it got resolved.
Voila! I didn't have to update anything in my eclipse.ini .
I have windows 7 64 bit OS in which I used to work with eclipse Juno Service Release2 version and Oracle JDK 1.7. Now as per my new project requirements I had to change my JDK from Oracle JDK to OpenJDK 1.7. I have un-installed all the other jdk's from my machine and installed OpenJDK1.7(64 bit version). Now I am facing issues with eclipse, I am able to open eclipse IDE but if I perform any operations like opening an existing project or trying to run any programs/project it is getting crashed or getting hanged. I have to end the process from the taskbar and try again and again. Below is the popup screen that I am getting after eclipse crashes.
Can some one tell me how to resolve this issue? I have seen some blogs saying there is a bug with eclise and OpenJDK with Ubuntu and mac OS but no issues reported for windows. So if there is way to fix this issue please let me know (or) please suggest any eclipse version the is compatible with OpenJDK1.7 and windows7.
Here is my version of solution to my issue which was mentioned above.
Installed Oracle JDK1.7 on my system and did not set the path for this. I have updated the eclipse.ini file with (found in eclipse root directory)
-vm
C:/Program Files/Java/jdk1.7.0_79/bin/javaw.exe parameter. so that Eclipse starts with Oracle jdk
and in
Eclipse->Windows->Preferences window
under Java->Installed JREs->Add(under Installed JREs)
added a new entry to point out the OpenJDK1.7 version so that my project uses OpenJDK version. This solved unusual crashing of Eclipse
I'm re-installing Eclipse, after I installed Android Studio. To do so, I deleted and re-installed all Java installations. Now I can't start Eclipse even I have jdk and jre installed on my machine. I'm getting this message " A JRE and JDK must be available.
Any ideas what I suppose to do?
If you are using Windows.
Install the Eclipse according to the system you are using i.e., is it a x64 or x86, and Install the Java x64 and x86 Accordingly.
how to know my PC running the 32-bit or 64-bit version of Windows?
this should help.
Please help :( My Eclipse Indigo wont launch. It shows the small blue rectangle and then hangs on that. If I then bring another window infront of this the blue square is now grey. There is no error and there is no error log file in the .eclipse folder.
My Ubuntu 12.04 has been acting funny. The software installer doesnt work and there are errors in the update manager. I finally did command line -update using apt-get and since then my eclipse has been broken.
System :
Ubuntu 12.04 X 64
java -version
java version "1.7.0_11" Java(TM) SE Runtime Environment (build 1.7.0_11-b21) Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)
I've been burned in the past by the Eclipse package bundled in Ubuntu's repositories. I would recommend downloading directly from Eclipse's website and run from there.
If you're having problems launching the Ubuntu-version, extracting and running manually should give you some indication that the problem is with Java or Eclipse.
I installed JBoss Tools on my Eclipse Juno. It worked, then when I click the tab design/view/ whatever it is except the source on my JSP window, It said that JBoss tool for JSP editor cannot run on my 64-bit Eclipse, JRE7, and Windows 7.
I've been browsing all over the place, some forums say you have to change your JRE to 32-bit. After that I installed JRE7 32-bit, restart and I tried to see the Java on Control Panel.
When I clicked Java tab on Control Panel, it said
Couldn't open \lib\i386\jvm.cfg.
I tried to checked on CMD, I typed java -version then it displayed
Unable to load native library: Can't load IA 32-bit.dll on AMD 64-bit platform.
I advise you to uninstall all Java instances, then start again.
Install 64-bit JDK first, set up your normal development tools to use it. Then install the 32-bit JDK but don't install the public JRE. Then configure a separate instance of Eclipse to use the 32-bit JDK. (I'd keep a separate, normal 64-bit Eclipse around, because 32-bit means you are limited to about 1.5Gb of heap for Java)
