I have never used Dr. Java before, so on it's first run I opened my completed .java source and went to Tools menu and selected Test Current Document. Dr. Java informs me that the test files may not be compiled. Closing the dialog results in an hourglass that never goes away. Can only rightclick on titlebar to select close application to shut down Dr. Java.

We need to try to reproduce this. I think this may have been fixed with
Empty file throws RuntimeException (bug 2564924)
https://sourceforge.net/tracker2/?func=detail&atid=438935&aid=2564924&group_id=44253
Seems to be fixed. Reproduction of the freeze resulted in the hourglass not showing.
