When I try to use an application with the following command on Ubuntu:
javaws http://example.com.br/remote_example.jnlp
or simply type
javaws
The followin error shows up:
Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /usr/lib/jvm/java-6-oracle/jre/lib/amd64/libdeploy.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
I've searched on Google, but didn't find the answer. I'm sure i'm using 64 bit Ubuntu with 64 bit 1.6 jdk, my coworkers are using the same set up but have no idea what this message is about.
The problem is the java 6 loading screen pops up but after that no signal of the application being opened.
I've installed execstack with apt-get and run execstack -c on the library, the message doesn't show up anymore, but the application still won't open.
Running this on the command line solved the problem:
update-alternatives --config javaws
And then selecting the 1.6 jdk instead of any other appearing there.
For some reason it was using the my java 8 jdk even though my $JAVA_HOME variable was set to jdk 1.6 path.

sbt fails with a cryptic error on issuing any command (compile, assembly, clean or any other).
$ sbt --version
error: error while loading String, class file '/modules/java.base/java/lang/String.class' is broken
(class java.lang.NullPointerException/null)
I am on a machine running macOS, and sbt was installed via homebrew. I have tried upgrading to the latest versions of sbt (1.3.10), but the error still persists.
The issue is documented on the SBT Download page.
Homebrew maintainers have added a dependency to JDK 13 because they want to use more brew dependencies (brew#50649). This causes sbt to use JDK 13 even when java available on PATH is JDK 8 or 11. To prevent sbt from running on JDK 13, install jEnv or switch to using SDKMAN.
I was able to resolve the problem by using JDK 8 via jEnv.
Since sbt documents JDK 8 and 11 as compatible versions
We recommend AdoptOpenJDK JDK 8 or AdoptOpenJDK JDK 11
try controlling which JDK is used by sbt via -java-home setting which can be configured system-wide via sbtopts run configuration
/usr/local/etc/sbtopts
or per-project basis via
<project-root>/.sbtopts
For example, to configure JDK used by sbt in current project, try setting in .sbtopts
-java-home /Users/picard/.sdkman/candidates/java/current
This is what solved my problem on my Mac.
brew uninstall sbt
Install sdkman
curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"
Install sbt via sdk
sdk install sbt
I had the same issue recently. What worked for me is to install SDKMAN(https://sdkman.io/)
$ curl -s "https://get.sdkman.io" | bash
...
$ source "$HOME/.sdkman/bin/sdkman-init.sh"
...
After installation, I wanted to see what versions of Java I can install. So I simply run this command to list all the available versions of Java
sdk list java
Choose the version you want to install (recommend installing either 8 or 11 as mentioned above) and simply run the command with the identifier that specifies your version from the list
sdk install java 11.0.3.hs-adpt
After installation, it set the Java 11 to default on my system. I then ran the sbt command again and it worked.
If you are using SDKMAN then in some cases certain versions of Java (i.e. JDK) from different vendor might help.
E.g. I was using Amazon Correto JDK8 (version 8.332.08.1-amzn) and it could not properly build my sbt project in IntellIJ IDEA, so I've switched to using Zulu's JDK8 (version 8.0.332-zulu) as default java version.
Hope this helps and good luck. :)
I am trying to use Eclipse CDT under Ubuntu 18.04 LTS.
I get the same error as many others, but I could not find a solution in what I read.
I try to launch with
$ eclipse &
OpenJDK 64-Bit Server VM warning: Ignoring option MaxPermSize; support was removed in 8.0
and I get
/home/user1/.eclipse/org.eclipse.platform_3.8_155965261/configuration/1551271296090.log
When checking /usr/lib/eclipse/configuration/config.ini (as per this) I found the following lines (among others)
osgi.framework=file\:plugins/org.eclipse.osgi_3.8.1.dist.jar
osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.301.dist.jar#1\:start
org.eclipse.equinox.simpleconfigurator.configUrl=file\:org.eclipse.equinox.simpleconfigurator/bundles.info
As for the first two lines, I have files
$ locate eclipse.osgi_
/usr/share/java/org.eclipse.osgi_3.8.1.dist.jar
$ locate simpleconfigurator_1
/usr/lib/eclipse/plugins/org.eclipse.equinox.simpleconfigurator_1.0.301.dist.jar
Nevertheless:
/usr/share/java/org.eclipse.osgi_3.8.1.dist.jar seems to belong to no package (a remnant of some old package?), since
$ apt-file search /usr/share/java/org.eclipse.osgi_3.8.1.dist.jar
gives no results.
I have ver 3.9.1

You are probably using an older Eclipse version that does not work with Java 9 or higher:
If using Java 9 or newer please use Eclipse 4.7.1a or newer as it contains fixes in Eclipse launcher to add all JVM modules.
Do one of the following to solve the problem:
Use Java 8 to run Eclipse (a JRE/JDK can be put in the subfolder jre of your Eclipse installation or be specified in the eclipse.ini file)
Upgrade Eclipse (recommended).
Complete error message:
The JDK is missing and is required to run some NetBeans modules
Please use the --jdkhome command line option to specify a JDK installation or see http://wiki.netbeans.org/FaqRunningOnJre for more information.
Some details: I just installed Netbeans on Linux mint for the first time and when I start it when its turning on modules this error message appears. But I do have jdk installed.
$ java -version
java version "1.8.0_66"

Find the file [netbeans installation directory]/etc/netbeans.conf
Luckily, Linux has a find helper like
find /home/ -name "netbeans.conf,
in which you can change the /home/ to a location where you want to search.
I found it at /usr/local/netbeans-8.1/etc/netbeans.conf
Once, you found the file, the following property needs to be set:
netbeans_jdkhome="[jdk_path]"
where you can find the jdk_path using:
update-alternatives --config java
In my case, I found it at /opt/java/jdk1.8.0_191
[Solved] For Mac OSX 10.11 (El Capitan).
Solution may be similar for other Unix-based systems.
The problem may have occurred because I inadvertently installed the jre
prior to installing the jdk. I uninstalled the jre, installed the jdk
and reinstalled NetBeans but the problem (popup window) remained.
However, the fix was fairly simple.
1. Make sure NetBeans is not running.
2. Make sure the jdk is installed.
3. Determine the location of the jdk:
The jdk location can be determined by entering the following (in Terminal):
$ /usr/libexec/java_home
For my system, the output was:
/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home
4. Edit the NetBeans configuration file to indicate the location of the jdk.
Near the bottom of this Netbeans configuration file (or equivalent for your NetBeans version):
/Applications/NetBeans/NetBeans 8.2.app/Contents/Resources/NetBeans/etc/netbeans.conf
Comment out the following line (insert a # before the first character):
#netbeans_jdkhome="/Applications/NetBeans/NetBeans 8.2.app/Contents/Resources/NetBeans/bin/jre"
Then, add the following line (or equivalent for your jdk version):
netbeans_jkdhome="/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home"
Then, save and exit the editor.
5. Start NetBeans (no more popup window indicating that the jdk is missing).
When netbeans has problems trying to find the path of the jdk, it's mainly because the version of the jdk does not match. Open the file C:\Program Files\NetBeans 8.2\etc\netbeans.conf, and verify that netbeans_jdkhome = "C:\Program Files\Java\jdk1.8.0_111".
Open netbeans.conf
sudo nano "/usr/lib/jvm/java-8-oracle/netbeans.conf"
Set proper sdk path:
netbeans_jdkhome="/usr/lib/jvm/java-8-oracle"
Exit Ctrl + X and to save changes Ctrl + T
This error showed up when I updated the Mac to Mojave. To fix, I edited the netbeans.conf file with the current jdk by using Terminal to find the correct jdk. Type
/usr/libexec/java_home -V
Here was my output.
Matching Java Virtual Machines (4):

1.8.0_25 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home
1.7.0_79 (x86_64) "Oracle Corporation" - "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
Entering the first jdk listed did not work.
I edited the conf file with the second one listed:
netbeans_jdkhome="/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home"
Restarted Netbeans. That fixed it.
This worked for me
1. install full JDK
2. either edit <netbeans-IDE-installation>/etc/netbeans.conf
2.1 unmark netbeans_jdkhome
2.2 link to JDK location e.g. /usr/local/share/java/jdk1.6.0_07/
3. or use --jdkhome command-line option e.g. ./bin/netbeans --jdkhome /usr/local/share/java/jdk1.6.0_07/
take care with the "/" at the end

Find and open this file /etc/netbeans.conf
If you see netbeans_jdkhome="C:\Program Files\Java\jre1.8.0_151" replace netbeans_jdkhome="C:\Program Files\Java\jdk1.8.0_131"
Save as adminstrator
Problem reseloved
In mid April 2019, Oracle has changed the JDK's licence. However, I was still able to solve this issue with NetBeans 11 and the JDK 12's open source build on my Windows machine. Just downloaded the open source JDK from https://jdk.java.net/ and extracted it. Then, in my NetBeans config file, I typed in the path to the extracted directory (NOT the "bin" folder!).
I resolved this problem by changing default version of JRE and JDK that I'm using to 11.x.x with following commands:
sudo update-alternatives --config java
sudo update-alternatives --config javac
I have downloaded eclipse classic x86_64 3.7 cocoa on my Mac Intel Core 2 Duo with snow leopard 10.6.8
I have extracted and copied the eclipse directory to Applications folder. When run,
I get following errors

Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode)
I have tried with eclipse classic 32 and 64 bit versions, with both i have the same problem .
I have also tried tweaking around priority of java version (32 or 64) under Java preferences.
Deleting /Library/Java/Extensions/log4j-1.2.15.jar resolved the issue.
Incase you are using ubuntu instead and had this problem, just go
cd /usr/java/packages/lib/ext/
sudo rm log4j-1.2.15.jar
sudo rm slf4j-*
I also had this problem and had nothing under /Library/Java/Extensions
You can notice that Eclipse reports: "The value will be overwritten using values from the preferences". So what you can do - visit Preferences > Network Connections and under 'Proxy Bypass' add Host: *
This has resolved the issue for me.
I set this to solve the problem:
http.sslVerify false in the egit config file.
I've a very weird problem:
after upgrading from Ubuntu 10.10. to 11.04 (new installation), I have weird problems with the Eclipse editor.
When writing Java code (new Project was created) I type
System.out.println("bla")
and then "out" is shown as rectangles only. Weird is that for about half a second I see "System.out.println" and then the editor changes it to System.[][][].println (not really [] (here I used two brackets), it is shown as rectangles).
See the attached file for an example.
This is very weird. I've never had this before with any Ubuntu, Java or Eclipse version.
Currently, I use: Ubuntu 11.04. Eclipse 3.6 (latest download from June 7th) and Java 1.6.0_25.
Eclipse and Ubuntu Terminal is set to UTF-8.
The problem also happens when using KDE instead of Gnome.
Any ideas what could be wrong here and how to fix this?
You have syntax highlighting set, and the font or font style for whatever type "out" is classified as in your syntax highlighting (class variable?) cannot be found.
I've solved this problem :)
We should install those packages and restart computer...
