[Jython-users] memory leak

[Sells, F. <fr...@ad...>]

I have a memory leak in an applet that uses the Python.exec() method
multiple times.  I though that would work since I overwrite the same Python
variable names with each invocation; however that is not the case.
contonious calls end up in a VM out of memory error

the jython registry has the following entry.  Will this solve my problem
(relating to memory leak :)  )?  Is there a difference between "soft" and
"weak"?

# List of choices for internal tables impl (PyJavaClasses canonical map
etc.),
# these are separated through ':' and tryed from left to right.
# For long running applications under java2, needing classes unloading,
# in order to have jython runtime automatically discarding 
# no longer needed info and avoding memory leakage, this can be set 
# to weak or soft (=> an impl. using weak-refs or soft-refs will be used).
#python.options.internalTablesImpl = soft
#python.options.internalTablesImpl = weak
