Description Johannes Michler CLA 2010-07-12 08:49:49 EDT 
Build Identifier: 20100617-1415

We recently updated to Java JDK 1.6.21(x86) on a x64 windows 7 (the same on a Win2k8R2x64 with x86 java/eclipse).

Now we cannot any longer "generate diagram code" for gmf. It gives us an error about missing permspace and then eclipse crashes. This is also the case when setting the XXMaxPermGen to 384m. When running eclipse with the old jdk everything is fine, so I think there are some changes in the hotspotVM/Garbage Collection.

This problems is on two different machines :-(

Reproducible: Always

Steps to Reproduce:
1. Chechout org.eclipse.gmf.examples.mindmap from GMF
2. Install latest Eclipse-GMF and latest JDK 1.6_21 (x86)
3.right-klick on mindmap.gmfgen and select "generate diagram code"
4. Eclipse hangs :-(

Comment 3 Johannes Michler CLA 2010-07-26 10:33:17 EDT 
Well this is a more-generic and not a gmf-problem, see http://www.infoq.com/news/2010/07/eclipse-java-6u21
