I have what appears to be the same problem, and here's a little more data.

Import causes no problems for me when NOT using Java Web Start.  But with JWS, some imports give the same error/Traceback as shown by offbeata.

Specifically: "import copy_reg" is what triggers this problem for me.  So a jython script reading simply "import copy_reg" will fail, whereas, e.g. "import sys" will succeed.

Unfortunately, many standard modules (e.g. string, re) import copy_reg internally, and so they also fail (the traceback in those cases points to their "import copy_reg" line).
