45	 * methods whose name corresponds to <tt>methodName</tt>. Sometimes, the symbiosis layer is not able
46	 * to disambiguate methods simply by means of the types of the actual arguments. In that case,
47	 * this 'cast' method can be used to manually disambiguate methods as follows:
48	 * <tt>jObject.methodName.cast(JClass1, JClass2)(arg1, arg2)</tt>.
49	 * 
50	 * <tt>jObject.methodName.cast(JClass1, JClass2)</tt> evaluates to a java closure that only
51	 * contains those overloaded methods whose parameter types exactly match the ones given.
52	 * 
53	 * @param types an array of JavaClass objects
54	 * @return a new JavaClosure where the wrapped overloaded methods correspond to the given types
55	 * @throws XSymbiosisFailure when no wrapped methods correspond to the given types
