Build Identifier: 

When working with papyrus class diagram (included my own small profile), when I open the empty editor and try to add new element from palette eclipse hang up for a moment and sometimes I have Java.lang.OutOfMemoryError: PermGen space error. Is this error known?

Reproducible: Always

Steps to Reproduce:
1. Start Papyrus
2. Open diagram
3. Try to add some element (e.g class or enum)

Here are some info to avoid PermGenSpace errors:

I know how to change permgen space :) 
My Eclipse has now max permgen space set to 1 GB and problem still exist. 
Only when working with papyrus. We use papyrus tool in University. (9 users and all have this error at least one time. )

Just to make sure, can you share the jvm arguments you set in the eclipse.ini file ?

Comment 5 Wojciech Trocki

2011-07-01 11:03:49 EDT

Ini file content related with jvm memory usage:

-Xms140m
-Xmx512m
-XX:PermSize=512M
-XX:MaxPermSize=850M

I think that resizing max perm size do not resolve this problem, because in some situations permanent generations grows to infinite, but this is only my own opinion.

Comment 6 Yann Tanguy

2011-07-04 11:09:19 EDT

Probably not, I'm currently using -XX:PermSize=64M -XX:MaxPermSize=128M  -Xms40m -Xmx1024m and did not face the same issue (I also tried yours without trouble).

You are currently using Indigo with Papyrus 0.8.0 right ?
Which OS and JRE are you using ?

Yes.

Win XP SP3. JRE 1.6.21 

When monitoring memory usage using tools in jdk (with no support for permanent generation :( ) the most memory consuming place is a creation a new model using wizard with opening editor.

Comment 8 Camille Letavernier

In the current version, Papyrus runs correctly with less than 512M of PermGen space (256m is enough in most all cases)

I close this task
