when I use jython to import from a jar as a user, I get the following
>>> import sys
>>> import adql
*sys-package-mgr*: processing new jar, '/usr/share/java/adql-1.3.jar'
*sys-package-mgr*: can't write cache file for '/usr/share/java/adql-1.3.jar'
*sys-package-mgr*: can't write index file
since the cache dir is not writeable for the ordinary user.
Maybe this should have been set to the user's home dir if started by a user?
