Description Dongmei Cao 2007-11-07 22:42:21 UTC

This is from this morning's code base (11/7) from TRUNK. I'm not sure if this also exists on the 6.0 branch. 

To reproduce:

- Start IDE with a new or old user dir (happens in both cases)
- Create a Visual Web Application
- Drop a Text Field and a Button onto the designer. 
- Now click on the JSP tab. The CPU goes up to 100% and I have to kill the IDE from Windows Task Manager.

It started to happen in build #4342 and probably caused by this commot:

Hi, could you please attach several full thread dumps (all threads and several subsequent dumps)? Dane, any ideas,
suggestions? Thanks

Comment 4 Jiri Skrivanek 2007-11-08 08:08:48 UTC

Comment 5 Vitezslav Stejskal 2007-11-08 08:10:27 UTC

Yeah, the line 130 looks suspicious. IMO the change was part of the fix for issue #121268.

Comment 6 Daniel Prusa 2007-11-08 08:13:53 UTC

Thread dump contains TokenHighlightsLayer$Highlights.moveNext() on the top - this is method I have changed to fix issue
121268, I will try to reproduce it and examine what's wrong.

Comment 7 Daniel Prusa 2007-11-08 08:50:06 UTC

Related commit in TokensHighlightsLayer rollbacked in trunk (there were no commit of this into release60).
This means that mark occurences still will not work reliably (a part of issue 121268). I will file it as a new issue.

/cvs/languages/engine/src/org/netbeans/modules/languages/features/TokenHighlightsLayer.java,v  <-- 
TokenHighlightsLayer.java
new revision: 1.10; previous revision: 1.9

Comment 8 Roman Mostyka 2007-11-08 09:41:26 UTC

With release branch build everything is OK. I can't reproduce this issue there.
