I think these messages are warnings. This means you can avoid them by
setting the python.verbose property to "error" either with Java's -D switch
(-Dpython.verbose=error) or in jython's registry file. You might loose
useful info though.

Check the registry setting "python.cachedir".  This is where it is trying
to write the cache.  By default it is the directory "cachedir" in the
sys.prefix directory (jython's installation directory).  Look for "cachedir"
in the directory where jython is installed and chmod there.

Only to find cachedir and change permissions, and possibly change the
python.verbose property.

Ugh, that's one long list!
