Description Jiri Kovalsky 2013-01-11 10:24:01 UTC

Build: NetBeans IDE Dev (Build 201301100107)
VM: Java HotSpot(TM) 64-Bit Server VM, 23.6-b04, Java(TM) SE Runtime Environment, 1.7.0_10-b18
OS: Windows 8

User Comments:
jkovalsky: Started debugging MemoryView Ant testing application, took its GUI snapshot, showed listeners on "Garbage Collect" button and then invoked "Set Logging Events..." action from "Event Log" node in "Events" output tab. Checked java.awt.event.MouseListener and clicked "OK".
Please note this is on Windows 8 with JDK 7 Update 10.

jrojcek: I used "Add Logging Listener" in the new GUI debugger. The exception occured after selecting an ItemListener and clicking OK button.

Comment 2 Jiri Kovalsky 2013-01-11 10:31:16 UTC

I think this is a P2 issue, because the feature (events logging) is not usable.

Comment 3 Marian Mirilovic 2013-01-11 10:43:18 UTC

Do we plan to fix it for 7.3 ?

Comment 4 Jiri Kovalsky 2013-01-11 10:51:06 UTC

If somebody else does not reproduce this on Windows 8, I do not insist on fixing this to 7.3. Your evaluation Martine?

Comment 5 Martin Entlicher 2013-01-11 11:19:27 UTC

I've reproduced the problem on Linux as well.
I'm going to investigate how to fix...
If this would be reasonably fixable, I'd vote for integrating the fix into 7.3.

Comment 6 Martin Entlicher 2013-01-11 14:38:48 UTC

It's a class loader issue.
I've fixed it in trunk changeset:   244363:47c8af772632
http://hg.netbeans.org/core-main/rev/47c8af772632

If it works well, I'd integrate it into 7.3, if approved.

Comment 7 Jiri Kovalsky 2013-01-11 14:48:09 UTC

Sure, I will verify the fix once a trunk build is available.

The change seems fine to me.

Comment 11 Martin Entlicher 2013-01-14 14:01:36 UTC

Upgrading to P1, since it's a showstopper.
