> In PySpark ML wrapper.py, the abstract class {{JavaWrapper}} has a static variable {{_java_obj}}.  This is meant to hold an instance of a companion Java object.  It seems as though it was made static accidentally because it is never used, and all assignments done in derived classes are done to a member variable with {{self._java_obj}}.  This does not cause any problems with the current functionality, but it should be changed so as not to cause any confusion and misuse in the future.
