[antlr-interest] Problem with antlrworks (1.1.7 and 1.2b) and Python target (generation/debugging)

This looks like as if the ANTLR version included in ANTLRworks has a disconnect between the Java target and the Python target. In other words, Python isn't uptodate there. Use the workaround until a new version of ANTLRworks is released.
