Message7101

I encountered a problem with running unit tests. After a while of experimenting it seems that it is related to some kind of path information that jython embeds in the generated class file. I'm running the session below on windows with Jython 2.7a1.

Notice that when I launch the interpreter with a different path (first with a preceding driver letter, then without), it fails at the second launch with a strange path related error. When I delete the generated .class file, and retry, it works fine (but now an attempt to launch it again with a drive letter will fail with the same error, and I need to delete the class file again).
