I am still getting the same issue on Netbeans IDE Dev 200807221016 build.Is that code fix ported on this build?
I am not sure if I can re-open the issue.

Thanks,
Sreekanth
Comment 48 Jaroslav Tulach 2008-07-23 07:59:40 UTC 
No, the change has not yet propagated to daily build. If you want to test it, you can get build from
http://deadlock.netbeans.org/hudson/job/laziness/
however it is just base IDE for Java, not the full IDE with everything.

Why do not you wait for the fix to be integrated to main-golden before reopening?
Comment 64 Marian Mirilovic 2008-07-25 13:54:11 UTC 
Ivan, please wait for integration into main-golden. This issue will be updated by "qa" user once it's done.

The new reports are all using older build than the build #200807291401.

Let's see if a report from newer build appears.
Comment 78 Jaromir Uhrik 2008-12-11 09:12:39 UTC 
Marking as verified.
