Then the fix is fine. Please add the CR that causes this regression to the see also field.

Hi Xuelei

I don't quite understand the bug report. Certainly it's good to prevent
that NPE, but why must the cipher suites be ordered? It seems it's not
ordered before the new HashMap.
No, it was not ordered because of a regression.

Is this a regression or an RFE?
It's a regression. We used to use TreeSet to sort the cipher suites. But
later it is miss-updated to use ArrayList rather then TreeSet in a bug
fix. Then the order was lost.

We need to sort the cipher suites because the order is the preference
when TLS handshaking selects a proper cipher suite. Please refer to TLS
specification about the order, page 41, RFC5246:

    cipher_suites
       This is a list of the cryptographic options supported by the
       client, with the client's first preference first.

You'd
better add some explanation in the bug report.

I will.

Hi Weijun,

Would you please review the fix for CR 7174244.
      http://cr.openjdk.java.net./~xuelei/7174244/webrev.00/

There are mainly two updates in the fix. One is to have
Krb5ProxyImpl.getServerKeys()  to check null return value of
Krb5Util.getServiceCreds(). The other one is to have cipher suite order
to be independent from HashMap implementation.  TreeSet is used to
replace ArrayList so that the cipher suites order are sorted
automatically.

Thanks,
Xuelei
