Hello everyone,

I installed a fresh copy of Indigo Build id 20110615-0604, and then installed the plugins for Xtext2, EMF, OCL, XBase and MWE through the update manager. Everything worked fine.

I have an Xtext 2 Project, which I implemented on an Windows XP machine running Eclipse Indigo RC and Xtext 2.

I installed the fresh copy of Indigo on a new machine, running Windows 7 Enterprise with SP1. My current JRE version is:

java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

When I start Eclipse, everything works fine, I can open the projects in my workspace and continue implementing. But when running a project as a new Eclipse instance (typically for Xtext Projects as they generate Eclipse editors), I get the exception

!ENTRY org.eclipse.ui 4 0 2011-06-28 14:57:41.478
!MESSAGE Unhandled event loop exception
Error while logging event loop exception:
java.lang.OutOfMemoryError: PermGen space

The new Eclipse instance starts successfully, but when I open a file within my project, Eclipse freezez/crashes and shows the above error in the console.

I double-checked and I am running the 64-bit Windows Version of Eclipse Indigo with a 64-bit Version of the Sun JRE.

Aditionally, I increased the PermGen size in the eclipse.ini file and in the Run Configuration. No use, I still get the PermGen space exception. Here's my eclipse.ini file:

-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.100.v20110502
-product
org.eclipse.epp.package.rcp.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
1024M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
1024m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms256m
-Xmx1024m

and the settings in the Run Configuration are as follows:

-Dosgi.requiredJavaVersion=1.5 -Xms512m -Xmx1024m

I also uninstalled and then reinstalled the JRE and restarted my computer.

What could be the problem? Oh, and I also read multiple topics about this exception, including this one. Nothing helped. If you need more details, please ask.

Thanks in advance.

It isn't clear from your post whether the exception is getting thrown in your Eclipse development instance or the instance you launch to test out your editor. I'm assuming it is the test instance that you are launching. If this is the case, changing the perm gen size in the development version of Eclipse will have not effect on the problem. The test instance is launched as a separate VM and has its own perm gen size.

The arguments you have added to the launch config pertain the heap size of the launched VM not the perm gen size. These are two different things. Try using -XX:MaxPermSize=512m instead of the -Xm arguments.

Note that the max perm size argument isn't a standard vm argument and it can change depending on the version of the VM you are running. Make sure that the argument is appropriate for your VM version.

Yes, it was the test instance I was having problems with. I replaced the line

-Dosgi.requiredJavaVersion=1.5 -Xms512m -Xmx1024m

with

-Dosgi.requiredJavaVersion=1.5 -XX:MaxPermSize=512m

in the Run Configuration and it workes, indeed! Thank you very much for the tip!

Regards,

Darie

Thank you very much!

This solved the very same problem I had with my 2nd instance of Eclipse 3.7 running as 'Run as application' from a 1st instance of Eclipse 3.7.
I experienced this error evertime when the already running 2nd instance of Eclipse used a function from the JDT for the first time, i.e. opening
a Java file or expanding the method level of a java source file from the Project Explorer.
The above mentioned settings solved that issue instantly.
