Communicating JSON data between Java and Python

[aghasemi]

Describe the problem
Is there a "recommended" way to pass JSON data between Java and Python code, apart from serialising it first?
There are many JSON parsing libraries for Java. Do any of them work better with JEP?

In my use case, when I get a JSOn object as return value of Python code and pass it back later to another Python code ( in the same JEP Interpreter), it does not have the keys it is supposed to have. Also passing a Jackson ObjectNode to Python does not work. Is there any way to make it work? Any code sample maybe?

Many thanks.
