MethodHandleImpl.makeGuardWithCatch has special invokers (GuardWithCatch.invoke_L*) for methods with arity up to 8. When method arity is larger, generic invoker (GuardWithCatch.invoke_V) is used. Generic invoker expects GuardWithCatch.target & GuardWithCatch.catcher method handles to have (Object... av)Object type, but they can reference arbitrary methods, so type conversion is needed. makeSpreadArguments takes care of parameters' type conversion, but return type is left as is. That's the reason why GuardWithCatch.invoke_V fails to invoke both target or catcher. The fix is to add return type conversion on both paths. Testing: failing test, test/java/lang/invoke/ Thanks!
