Request for review: 8019267: NPE in AbstractSaslImpl when trace level >= FINER in KRB5

[Weijun Wang]

Hi All

An NPE was suppressed in jdk8 with a simple if. This new fix tries to 
output useful info even for a null argument.

Please review the code changes at

   http://cr.openjdk.java.net/~weijun/8019267/webrev.01/

The added test makes sure logging does not crash and the output is 
informational.

Thanks
Max
