Research direction

Start with pyspark/spark_support.py, especially serializeToBundle and the SimpleSparkSerializer initializer at line 39. Trace how _jvm().ml.combust.mleap.spark.SimpleSparkSerializer is made available in the Spark integration and reproduce the reported TypeError. Done means the affected PySpark serializer can be instantiated without the reported JavaPackage error.
