> Method with argument of type Class cannot be found by metaClass.getMetaMethod():
> {code:java}
> class A {
>     // cannot be found by getMetaMethod
>     def met1(Class clazz) {
>         println clazz.name
>     }
>     // a workaround
>     def met2(List<Class> clazz) {
>         println clazz.get(0).name
>     }
> }
> A.metaClass.invokeMethod = { name, args ->
>     def metaMethod = delegate.metaClass.getMetaMethod(name, args)
>     if (metaMethod) {
>         metaMethod.invoke(delegate, args)
>     } else {
>         println "Method $name not found on $delegate"
>     }
> }
> def a = new A()
> a.met1(A) // prints Method met1 not found on A@1c804...
> a.met2([A]) // prints A
> {code}
> It could be caused by ambiguous nature of *getMetaMethod* which accepts array of Object or Class as well, in case of Class as an argument it cannot find method correctly.
