Description Stanislav Aubrecht 2012-02-16 14:08:12 UTC

The IDE deadlocks when attempting to drag a TopComponent when running under JDK 1.7 update 4 b11 (developer preview).

Switching off 'Drag Window Image' and 'Transparent drag window image' in Options prevents the deadlock. However the window is dropped to wrong location due to d'n'd bugs in the JDK.

Standa, is it our issue or JDK's one ?

i'm not sure yet. it could be both JDK bug and a problem on our side as well. i'll have to check if there's a new version of JNA library that works better with JDK 1.7 on mac.

Ok, would be important to know it. In case it's JDK bug we will escalate, otherwise this needs to be fixed soon, to get it into 7.1.1 .

Comment 4 Antonin Nebuzelsky 2012-02-23 19:53:48 UTC

Filed #7148289 for evaluation on the Java side.

Comment 5 Tomas Danek 2012-03-19 14:04:57 UTC

isn't this about the same as http://netbeans.org/bugzilla/show_bug.cgi?id=208276 ?

I can confirm deadlock still occurs when DnD TC in JDK 7u4 b16 , and that workaround works.

Comment 7 Marian Mirilovic 2012-03-21 13:47:16 UTC

We propose to disable Visual Effects in Window System settings for NetBeans 7.1.2 and leave this bug opened for later fix on JDK side.
