JSON Enabled function returns Error when Empty value is passed

After the adding JSON support for Java Fn function, if the function is passed an empty value, Fn returns:

{"message":"container exit code 2"}

Fn: Error calling function: status 502

The function does work with JSON data. If you pass:

{"name":"Bob"}

or even

{"name":""}

the function works fine. Tried modifying the function to test for null and isEmpty. Nothing like that worked. I'm guessing the function is throwing an uncaught exception.
