App refuses to start with NoClassDefFoundError: javax/swing/SwingWorker - rsoese@gmx.de - 2011-10-25
Hy,
I just wanted to give LRTimelapse a try but was not able to start the app. I read all the other threads about failing to start the app on OSX but nothing helped:
I installed the new Java from Apple
I started the jar only
I renamed the app
Without luck. The Terminal logs this exception:

That's really weird. And I honestly have no Idea what causes that error, I've never heard of a case like that. Could you please double check the java installation? The "Swingworker"-class that is not found normally is a core java class, so it should normally be there. Please give it another try and get back to me.

Das Problem besteht (natürlich) nach wie vor aber diese Forum berichtet das irgend ein Mac / Java Update den Swingworker "zerstört":

Okay, bitte berichte dann mal! Ich habe selbst leider keinen Mac, wäre daher an einer Info sehr interessiert.
