RFR: 8333857: Test sun/security/ssl/SSLSessionImpl/ResumeChecksServer.java failed: Existing session was used

[Anthony Scarpino]

Hi

I need a review for a client-server threading change that will hopefully address intermittent failures.  This change is similar to [JDK-8348309](https://bugs.openjdk.org/browse/JDK-8348309).  The functional testing is unchanged.

thanks

Tony
