Snjezana Peco commented on JBIDE-1753:
--------------------------------------

This issue is fixed within JBIDE-1105/JBIDE-538.
There isn't a memory leak when opening/closing the VPE editor.

Steps to reproduce:

- show heap status
- create some JSF project
- import the http://jira.jboss.com/jira/secure/attachment/12315941/JBIDE-675.tar.gz archive
- open/close the employee.xhtml file a few times

In JBoss Tools 2.0.0/2.0.1 memory will be increasing permanently and you can get OOM.
The current SVN or latest builds work correctly. The memory will be increased only when the editor is opened the first time

Increasing PermGen is related to Sun's JDK  and we can't fix it.  A workaround is setting the PermGen space to a higher value.
I am using -XX:PermSize=128M -XX:MaxPermSize=256M

> Below description of few open/close file test and results of memory consumption
> 1.Start of eclipse with no editors
>       heap memory usage  17MB
>       non-heap 38MB (CMS PermGen 35MB)
> 2. Open new empty xhtml
>       heap memory usage  37MB
>       non-heap 54MB (CMS PermGen 49MB)
> 3. Close newempty xhtml  (no editor windows)
>       heap memory usage  35MB
> 4. Open simply xtml (only html tags)
>       heap memory usage  44MB
>       non-heap 57MB (CMS PermGen 51MB)
> 5. Close simply xhtml  (no editor windows) 
>       heap memory usage  42MB
> 6. Open complex xtml with non html tags
>       heap memory usage  56MB
>       non-heap 58MB (CMS PermGen 51.5MB)
> 7. Close complex xhtml   (no editor windows)
>       heap memory usage  49MB
