Subject Re: Question on TCK11

The test in question used DatastoreIdentity. 

you said: 

"The classes in question have a set of fields that
uniquely form an *application identity*" and I'm just
saying no, they don't form an *application identity*,
because this test doesn't use application identity. It
uses Datastore Identity.

Ho hum, I guess I'm just grumpy because I didn't
expect the Apache TCK to be so different from the Sun
TCK.
