Doh. Sorry about this. I had run into this as well and was in the middle
of investigating the issue when it slipped through my list thanks to our
hectic office move recently :(

FWIW, backporting the framework is not adequate. Though the test
compiles after that, it still fails saying:

java.io.IOException: DerInputStream.getLength(): lengthTag=127, too big.


Brock Janiczak from Red Hat helped me out on that one and determined
that it was an additional bug whereby pdata was being regarded as
mandatory when it's optional:

http://hg.openjdk.java.net/jdk7/tl/jdk/rev/7360321c37e3

After that patch, the tests get further, but one still fails saying:

RABBIT.HOLE> dummy sends AS-REQ for krbtgt/RABBIT.HOLE
KrbException: Additional pre-authentication required (25)

That was as far as I got before I lost track :/

The failures all seem to be due to unrelated bugs however and I can
confirm that the ported patches do indeed fix the specific issues we
were seeing.

Sorry again for the slippage.

Cheers,
