for i in jp: print i

# gives infinite loop of ....

Should it not give an error "loop over non-sequence" instead?
This is jython 2.0 on Redhat 7.0 IBM vm cx130-20001124 AND dito on W2k Sun VM 1.3.0.

BTW: I am really impressed by your extremely nice work with Jython!!! 
I'm using it with apache jserv for servlets etc, as we have other people working on 
"normal" java servlets this integrates better that running cpython with mod_python.
Keep up the good work!
