I have the following problem. I'm occasionally getting a Jython
stracktrace which ends with
but only the Python part of the stack is printed, and it's quite
difficult to tell what's happening
without understanding which Java code is throwing NullPointerException.
If I create a trivial program where this happens, both Python and Java
stacks are printed, so it's
something specific to my program, or this particular usage of it.
I'm using Jython 2.5.1. Googling has hinted to me that there have
previously existed system properties
for this, i.e.
but as far as I can see neither of these properties exist any more.
Would appreciate any tips on how to debug this.
