Here’s a minimal program that tickles the error. It works on everyone’s machine except mine (so..you might not want to spend any time on this). My last (wrong) theory was that it had to do with an interaction between Sophos version 8 and Mac OS/X 10.9. But, fixing *that* did not fix *this*. Current status is that the program worked correctly ONCE after a reboot, and then failed; I suspect this is repeatable, but have not had time to test (I re-worked the program that needed this, so it’s no longer on my critical path).
Failure mode is that the OpenDialog box is invisible. The program behaves as if the dialog box has been displayed and is waiting for input. The program displays “calling showOpenDialog” and sits quietly, waiting for showOpenDialog to return.
Note that this might be an improper use of Swing code without actually firing up Swing - but the docs say it’s legal, and it has worked for a long time.
MacOS/X 10.9.2, Java 7 - both installed at the same time. Again - it works on other machines.
