MinimWatch troubles

[vkoechli]

I'm having problems with MinimWatch on Mac OSX after updating to 0.8.3 and installing the latest update (31).

MinimWatch will launch once and on exiting display an error message (see Attachment). After that, I can't launch MinimWatch again from the GUI until I sign off and on again. Activity Monitor shows no running MinimWatch process.

Using the command line I can re-launch and use MinimWatch successfully using MinimWatchLauncher in the App's Content/MacOS directory. On exiting the same error appears. In addition, a similar error message is printed in the terminal ("TrayControl: ObserverCache error: java.lang.ClassNotFoundException: sun.awt.image.MultiResolutionToolkitImage$ObserverCache") and the process hangs until killed with Ctrl-C.

The problem persists even after rolling back to the previous version (0.8.1). Only after deleting MinimWatch's folder in ~/Library can I use the older version. It appears the problem is with the latest update package (31).

Mac OS X (10.10.2) and Java (7 Update 75) are up to date. I'm attaching an error log (from ~/Library/MinimWatch).

Is anyone else seeing this? Any ideas how to fix it? Or is it actually a bug with update 31?

Thanks for any help
