Constructor0204 test expects IllegalArgumentException thrown due to wrong parameter type, something like this:

  Class params[] = {int.class};
  Constructor c = T.class.getConstructor( params );
  Object args[] = {int.class};
  T ob = (T) (c.newInstance( args ));

But VM throws ClassCastException with no stack trace during the invocation of a method handle when running with -Xcomp in the new core reflection implementation after JEP 416 is integrated. InvocationTargetException wrapping CCE is thrown instead.
