    Your terminal does not correctly interpret the output from javac, which is most likely an encoding issue.

    Be sure that any locale variable (“export” in Terminal.app) corresponds to the encoding expected by Terminal.app (check Settings, I’m not at a Mac right now). If all else fails, try “export LANG=” so plain English should be output.
