Calling Java that uses jep

[injo11]

We have Java code that uses Python through jep, but want to expose this Java code to Python (through JPype, so Python host) so that we can use our Java library from Python. Is this possible? Trying this out makes the Python host crash immediately. Is there some other solution to this? The Python called from the JVM (currently through jep) sharing the Python kernel with the calling Python host or something else (two different Python kernels for host and JVM initiated would be ok if possible)? This problem looks like the opposite of issues #1084 and #516, but those could possibly be related to a solution. So rather than using JPype in a JVM host through jep, we want to use a Java library that uses jep Python code, from a Python host.
