This is the second time this has happened to me. In this last occurrence, I made a change to a library that my module depends on. I compiled my jar, cut and paste the jar into the right place in the suite, and recompiled my linked module library. However, I neglected to recompile my main module, which had compiled classes that now called functions in my library that no longer existed. I ran my module, and it crashed during startup, issuing a 'method not found' exception. I fixed the problem, and recomplied. However, now whenever I try to run my module, all that appears is a JFrame with no content. The messages printed to stderr during startup are different too. I've cleaned and rebuilt, but only the empty JFrame appears when I run now. How can I restore my module to normal working order? The last time this happened, I had to abandon my module and start a new one.

I'd suggest to clean up your userdir. Reassigning.
Make sure you have deleted the user dir when you do a clean. Other than that there's not much to say, without steps to reproduce or some reporter-side investigation of the root problem. A dirty user dir is most likely.
