OK, so I’ve got another problem with the Java Media Framework.

I’m trying to register a custom Effect. The registration proceeds without throwing any exceptions, but then while executing a later statement as mundane as **setJMenuBar** , I’ll have **java.lang.reflect.InvocationTargetException** appear. Moving the registration calls only causes the exception to appear during similarly mundane statements.

If I remove the registration, no exceptions appear. Also, enclosing any offending statements in a try/catch block reveals no exceptions. I’m truly baffled.

Thoughts?
