Now that Ken has implemented the supporting bits needed by PI (and
after the current build starts working again) could you please:

1. Have IORInfoImpl.get_effective_policy throw the correct
   PI exception if it gets null back from the delegate.

   Ken's POA implementation of this does not throw the exception
   because that would cause it to have a compile time dependency
   on PI. So he returns null if the policy does not exist.

2. Turn on get_effective_policy unit tests.

3. Turn on register_initial_reference unit tests.

4. Turn on ServerRequestInfo.adapter_id unit tests.

Thanks,
Harold
