> Given a test case [1] and two interfaces [2] [3] in default package.
> (1) Run test case [1] on [2], both of HY5's and RI's Proxy work well.
> (2) Run test case [1] on [3], HY5' Proxy fails [4] while RI works well.
> In conclusion, this is only a problem when the interfaces are undeclared "public" and located in the default package.
> Note: The reported defect only happened when the interface is undeclared "public" and located in default package. Thus please put this test case in the default package.
> Would you please help to review this patch?
