Stando, related to recent clipboard changes in trunk?

Created attachment 150729 [details] stacktrace I tried to create JUnit tests for teststorun package of JUnitSampleProjectAnt project. I unchecked option to create suite, selected Test Packages as destination and pushed OK button when IDE deadlocked.

Created attachment 150860 [details] stacktrace In an existing project, I started the dialog to create a new Java class, named it, then changed my mind (planning to create a Java main class instead) and canceled the creation dialog. As soon as I clicked cancel, the IDE froze (with an "I-beam" cursor). It did not respond to any mouse clicks, and I ended up having to force-kill it.

core-main b7385956de2d
Integrated into 'main-silver', will be available in build *201412090001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-silver/rev/b7385956de2d User: S. Aubrecht <saubrecht@netbeans.org> Log: #248122 - refined fix for #247585 to be active on Windows only
Reproduced in NB 802 + 802patch
(In reply to Alexander Simon from comment #13) > Reproduced in NB 802 + 802patch Would be nice to add fresh steps to reproduce and fresh stack trace when reopening.
btw, the fix is not in 8.0.2 now, is it? It's been fixed only in Dev so it makes sense people are able to reproduce still in 8.0.2.
