Programmers place all arguments to the method in an args variant array that immediately follows the methodID argument.

This is generic version, where our plugin translates between native Xojo data types and Java data types. We support conversion of boolean, byte (integer), char (integer), short (integer), int (integer), long (int64), double, float (single) and Java objects. Objects can be JavaObjectMBS or subclasses including JavaStringMBS and the JavaArrayMBS subclasses. For your convenience you can pass in string and we convert to JavaStringMBS for you.
