thread dump

NetBeans IDE goes into continuous CPU load randomly when trying to do code formatting operation on Win 7 x64. After that - code formatting and navigator doesn't works at all, showing continuous business.
External src scans, SVN & etc is disabled.
Tried to run app with administrator privileges and in compartibility mode - doesn't solves a problem.

also same situation with auto completion, somehow it hangs ide on 100% load, then showing constant 'please wait' popup when toggling.

Could you please take and attach 2-3 thread dumps while running into this? Thanks.

Another snapshot from a PHP user, when the cpu is consumed too much. 

The snapshot is from NB 6.9.

is it possible for me to have reproducible case(the project or artificial extracted as simple as possible code) where could I reproduce? If so, then I hope I'm ready to fix it pretty soon, thanks

Issue stoped reproducing since i disabled all major team features, as svn refresh, also disabled external refresh, disabled spellchecker plugin, spellchecker dictionary plugin, hudson plugin and installed JIRA team plugin. Maybe it's not the reason, just working with other code.
I have another couple of thread dumps of this issue, when tried to work in compartibility mode, so i'll attach it now.

reproduced today when _> turned on external php vars autocompletion <_ & tried go to definition of native 'yii framework' method 'getPathOfAlias' on this code. It has pretty much recursion though.

Fixed in trunk now:
http://hg.netbeans.org/web-main/rev/2b54057d9d46

This issue might be also fixed into release 6.9.1, but I need verification that
the fix really helps. Thanks to rogojine I was able to reproduce the never
ending loop, so at least in this usecase this fix works.

Problem description: never ending loop for type inference when e.g. method "a"
calls method "b"  and method "b" calls method "a" (on different types but with
the same name). 

Justification for fixing it into relase 6.9.1:
-many duplicates
-complains about it on forums, blogs

For verification use please #2079 build (or newer):

PLEASE VERIFY
