RFR 8080911: sun/security/krb5/auto/UseCacheAndStoreKey.java timed out intermittently

Hi All

Please review a code change at

   http://cr.openjdk.java.net/~weijun/8080911/webrev.00/

I've limit the synchronized block to Config creation only and therefore 
won't deadlock with EType's class initialization.

Noreg-hard. The EType call is at class initialization and only run once 
in a VM session, which is extremely difficult to catch.

Thanks
Max
