return self.get_java_object().getValue()

When an attribute is an EnumerationValueAttribute, values are list not a single element (unlike String or a number).
Calling 'getValue()' on Java Object raises an Error.

'getValues()' should be called and result should be wrapped in a list.

Yes we should return something loke:

create_e_list(self.get_java_object().getValues(), EnumValue)
