There are some known issues with the current SSLSocket test template (test/javax/net/ssl/templates/SSLSocketTemplate.java):
1. the client or server can be blocked if the peer run into problems, as may result in intermittent timeout failure.
2. the server accepted connection may be not linked to the expected client. For example, some other test case may try to connect to a server socket port, unfortunately this port is actually opened by the server of SSLSocketTemplate. As may result in weird intermittent timeout failure

Need a new SSLSocket template and consider the noises above.
