Description Tomasz Borek CLA 2011-05-31 01:02:22 EDT 
Hi,

Wanted to get help with one bug I came across, that manifest itself when I work with JS files in Java EE perspective. Even basic operations (moving down or up through file, highlighting, copying code, etc.) quickly throw off internal error or unhandled loop exception. 

Noteworthy: 
1) doesn't happen if I use JSEclipse for JS files, but if I forgot to switch perspectives, boy, I'm in trouble quick. 
2) I extended heap space to 512. This 'only' prolongs time when Eclipse works furiously in the background just before crash.
3) See MAT, below.

> What steps will reproduce the problem?
Tricky one, as it did not occur immediately. I used to work with both JSEclipse and Java EE perspectives 'handling' JS files, and it was OK. My colleagues warned me against Java EE perspective, yet warnings sounded hollowe since nothing happened. They were surprised. Still, after three weeks with daily work being done in Eclipse, Java EE stopped being able to handle JS files. It's now often enough to open JavaScript file while in this perspective, to get sluggish responses, basic operations are delayed (even several seconds!) and crash happens sooner than later.

> MAT
I installed MAT (Memory Analyzer Tool) and *will attach it's report later*. It detected no leaking plug-ins installed, and found this (note, my code wasn't even working at the time, it's just Eclipse):

Used heap dump 500,4 MB

2) org.eclipse.jface.text.TextViewerHoverManager$4 @ 0x1b7a32f8 Text Viewer Hover Presenter Thread 

took respectively 245,8 and 147,8 MBs of heap. These are primary suspects for leaks.

I will also *attach Eclipse error log later today*.

PS. I can't get into Eclipsepedia to see keywords, so some of them might later change, once server will reply.

CFEclipse warnings can be safely ignored:
http://groups.google.com/group/cfeclipse-users/browse_thread/thread/21d48af5836e8ac4?pli=1

PermGen fix with launcher args off and using VMargs also does not change a thing (not that I thought it will):

MAT report from recent crash

In case heap space was the problem, I did the following:
- tried extending it via vmargs (ini file) to 512MB
- installed MAT
- added -XX:+HeapDumpOnOutOfMemoryError to have heap dumps when running eclipse (ini file again)
- ran MAT against the dump to have the leak suspects report

Sounds like a duplicate of bug 345797.

Thank you Nitin.

> Sounds like a duplicate of bug 345797.

Can this be closed now? Was it a duplicate?
Comment 6 Tomasz Borek CLA 2011-08-22 05:35:13 EDT 
Yes, that seems a dupe, and even though the other bug does not resolve this issue, this can be closed. Sorry for delay in answering.

regards,
Tomasz
