Tom Erbe found a workaround, and describes it as follows:
> I just upgraded to QT 5 to check this out, and sure enough, the
> javamidi code wasn't working with QT 5. I then tried to start OMS
> Setup, and my machine froze, so I dug in a little further. Here is

> 1 - Start the Quicktime Settings control panel. It needs to be run
> once before anything works. Check the Music section to make sure
> everything looks normal here.
> 2 - Remove all of the OMS Preferences and any Autosetups in the OMS
> Folder in the System Folder
> 3 - Reinstall the latest OMS (2.3.8)
> 4 - Restart
> 5 - Run OMS Setup
> 6 - Recompile your Java application
> After I did all this, my Java MIDI code worked once again. I think
> the problem is that the old OMS autosetup file conflicts with the new
> QT5 Music driver.
Hope this helps, if you're experiencing the same problem.
