Code Review Request JDK-8146387, Test SSLSession/SessionCacheSizeTests socket accept timed out

[Xuelei Fan]

Hi,

Please review a test update for JDK-8146387:

   http://cr.openjdk.java.net/~xuelei/8146387/webrev.00/

In the test case, javax/net/ssl/SSLSession/SessionCacheSizeTests.java,
an integer (createdPorts) is used to count the server sockets.  Every
server socket is created in a new thread.  The access and update to
createdPorts should be synchronized for multiple threading safe.

Thanks,
Xuelei
