Description Exceptions Reporter 2011-11-03 14:46:28 UTC

Build: NetBeans IDE 7.1 Beta (Build 201109252201)
VM: Java HotSpot(TM) 64-Bit Server VM, 19.0-b09, Java(TM) SE Runtime Environment, 1.6.0_23-b05
OS: Windows 7

User Comments:
arittner: CodeCompletion with Lookup.getDefault

tnleeuw: Typed 'sessionFactory.get'; that quickly resulted in a list of possible completiond.
Then added 'Cur' to select the completion 'getCurrentSession()' and that's what took so long.



Maximum slowness yet reported was 23359 ms, average is 8502

Comment 3 Milos Kleint 2013-01-09 12:39:08 UTC

it appears that the J2seLogicalViewProvider should not call initListeners() -> addLinbraryManagerListener() which can hang on synchronization

Comment 4 Tomas Zezula 2013-01-09 17:45:57 UTC

In reply to comment #3, probably in wrong issue.
There is no call to initListeners() in the snapshot, also the CC thread is not blocked by any lock.
The problem is in J2SELibrarySOurceForBinaryQuery listing project library managers.

Comment 5 Martin Balin 2016-07-07 07:16:54 UTC

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
