[8u-dev] Request for approval: 8044215: Unable to initiate SpNego using a S4U2Proxy GSSCredential (Krb5ProxyCredential)

[Wang Weijun]

Hi All 

This is a request to backport a jdk9 fix into jdk8u-dev. 

8044215: Unable to initiate SpNego using a S4U2Proxy GSSCredential (Krb5ProxyCredential)

   https://bugs.openjdk.java.net/browse/JDK-8044215

The fix is already included in jdk9 as: 

   http://hg.openjdk.java.net/jdk9/dev/jdk/rev/ee77bb0c8ae7

The patch for jdk8u-dev is identical to the one in jdk9.

The fix is low-risk, and isolated. An existing regression test updated to cover the change.

Thanks 
Weijun
