Doh! This was supposed to be fixed by release 2.5.3-12. Big fail /o\
My mistake was to change CACHEDIR_DEFAULT_NAME only.

The problem is that when the cachedir path is not absolute, it is
considered relative to the installation prefix: /usr/share/jython.

How about considering it relative to - say - $HOME/.jython instead?

Thanks,
