Code Review Request, JDK-8209916 : NPE in SupportedGroupsExtension

[Xuelei Fan]

Hi Jamil,

Would you please review the fix for the NPE issue:
    http://cr.openjdk.java.net/~xuelei/8209916/webrev.00/

The issue may happen if the client supports a SunJSSE provider known but 
not supported named group.

Thanks,
Xuelei
