I've been investigating an issue that I am currently having on Windows (7
and 8) with drag and drop in Java 8.
The issue I'm having is when I drop a file from Windows explorer onto
Netbeans the instance of Windows explorer from which I dragged the file
freeze until I close Netbeans.
I could reproduce it on the simple TopLevelTransferHandlerDemo from the
Java Tutorial [1].
After digging down the JDK8 code and comparing it to JDK7 code, I could
find a change in sun.awt.dnd.SunDropTargetContextPeer.
Reverting the change fixed the issue.
Searching the Mercurial repo [2] for changes in SunDropTargetContextPeer
showed that the change was introduced last June [3].
Since it is platform dependent and a fix to another issue, I am unsure at
what I can do more.

Thanks in advance,
