Re: a question about rmi sample

Ni hao!

Try to make sure that the attributes really are
loaded, for example do:
assertTrue(Attributes.hasAttribute(MyObject.class,
"remote"));

Also try to execute java with asserts enabled, ie:
"java -ea". You may get a different more helpful
error-message.

If this doesn't help you either I need to look deeper
into the problem. I can to that later this weekend.
