Problem seems only to occur on ea jdk7u40.
Please, generate thread dump at the moment you see the empty window, and reopen. Thanks. http://wiki.netbeans.org/GenerateThreadDump
Unfortunately it is not possible to generate the thread dump once the problem occurs. This seems to be a Mac OS issue: only rarely can jstack connect to the process.
