thread dump taken when cpu was 100% and netbeans was very sluggish

Description sstanojevic 2007-08-09 22:32:23 UTC 
Still unsure of the cause, but when I do "Navigate --> Go to class..." and open up a source file, it would seem that if
that source file is packaged in a fairly large jar bundle file, then Netbeans has some serious problems dealing with it.
 In my case, I have noticed this when I try to browse the Glassfish App Server's source files, which are conveniently
packaged in one big jar file.  That's why I think it may have something to do with the size of the source jar file.

The usual symptoms are that the netbeans java.exe process starts consuming 100% CPU for a minute or so, and at times I
will also get the "Out of memory" error.  This will happen practically on every single file I try to open up from that
source bundle.  It is very aggravating as it freezes the IDE for minutes at a time.  It is particularly aggravating when
I'm debugging my project where I need to jump around the various classes.  It takes me forever to do this.

This issue is not valid in current builds any more. Java support was completely
redesigned in 6.0 time frame. Please use NetBeans 6.0 and later.
