Some python types (in particular
GenericAliasandUnion) cannot be handled by the default->jvmhandler.Note on tests: The only way I could find to instantiate an object of type
types.UnionTypefor testing is directly with python syntax and the|operator. I don't know of a way to test objects created via syntax without creating global variables in the python interpreter (e.g. withrun-simple-string). For that reason, I've left the test for this out for now. I have tested by hand. Suggestions for good approaches to this welcome.Note:
types.UnionTypeis not the same astyping.Union, which can be used via__get_item__to produces objects of typetyping._UnionGenericAlias.
