Description mithridates 2010-11-30 09:22:18 UTC 
[ BUILD # : 201011300001 ]
[ JDK VERSION : 1.6.22 ]

rather complex jsf-webapplication with ICEfaces 2 components (beta1 or beta2).
Opening a large page (~400lines) results in a period of about 2 minutes parsing
(cpu at 100%). After that (syntax-highlighting now shown) the used memory of
the IDE is at about 640m and increasing. 
Max 15 minutes later (in this time the nb-processlist shows repeatedly
"scanning facelets libraries") the heap is full (OOME is thrown), the IDE
stalls completely. 
Memory increase can be speeded up by setting the cursor behind a tag-attribute.
Closing the page does not free memory.
I did not see this with the nightlies before 201011300001.
Comment 1 Petr Jiricka 2010-12-01 09:52:24 UTC 
Hi, I assume that your pages are in the .xhtml format, right? Or are they .jsp?
Comment 2 Marek Fukala 2010-12-01 10:13:51 UTC 
possibly regression of the fix of issue #191041 Memory leak in JsfSupport.INSTANCIES
Comment 3 Marek Fukala 2010-12-01 10:17:37 UTC 
Its bad! It is definitively a regression of the change. The JsfSupport instance is not cached at all but computed each time one asks for it.
Comment 4 Marek Fukala 2010-12-01 11:40:29 UTC 
fixed in web-main#6ec614cd9a84

I'm really sorry for the problems, it was just a silly mistake, please update to newer build once its integrated.

Thanks for the report!
