RFR: JDK-8135055.java.util.Date.after(java.sql.Timestamp ) does not return correct results

[Rachna Goel]

Hi,

Please review fix for JDK-8135055.
Bug:   https://bugs.openjdk.java.net/browse/JDK-8135055

Webrev: http://cr.openjdk.java.net/~rgoel/JDK-8135055/webrev.02/

Fix is to return getTime() if argument to  getMillisOf() is an instance 
of java.sql.TimeStamp.

Thanks,

Rachna
