> 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.
