> org.apache.geode.internal.net.SocketCreator#configureClientSSLSocket timeout for Socket
is being configured before starting SSL handshake only if passed "timeout" argument is larger
than 0.
> Having sslSocket.startHandshake issued without setting timeout can result to the blocking
of caller thread as in GEODE-2898, GEODE-3023.
> Below is the example of Handshaker thread stack-trace that got stacked:
