Comment 2 David Strupl 2014-06-02 14:25:05 UTC 
NbClipboard calls getContents()

sun.awt.X11.XClipboard.getContents(XClipboard.java:108)
   at org.netbeans.NbClipboard$GetContents.run(NbClipboard.java:437)

from non-AWT EDT. Not sure whether this is ok or not but it causes deadlock in 

java.awt.datatransfer.SystemFlavorMap.getFlavorsForNative(SystemFlavorMap.java:796)
vs
AWT lock.

Re-assigning to the platform component to evaluate.
Comment 3 Jaroslav Tulach 2014-06-10 08:33:56 UTC 
Why assigned to me? Btw. yesterday I saw a change in OpenJDK bugs related to clipboard, but I have not taken closer look and now I can't find the bug anymore

in the previous run of netbeans ide, the window has totally frozen.
Comment 7 Stanislav Aubrecht 2014-12-12 09:36:59 UTC 
This is a JDK bug (manifests on Linux OS only), see https://bugs.openjdk.java.net/browse/JDK-7155963

A possible workaround could be running NetBeans with -J-Dnetbeans.slow.system.clipboard.hack=false command line switch.
