Behavior changes for SSLSocket input stream shut down


The SunJSSE close notification checks for SSLSocket have been made less strict to conform to changes in the Transport Layer Security (TLS) RFCs.

If an application tries to close the input stream of an SSLSocket (via shutdownInput() method) without having received a close notification message from its peer, the SSLSocket will no longer:

  1. trigger the transmission of a TLS fatal-level alert to the peer, and
  2. invalidate the current TLS session.

The new behavior will still consider this condition an error and will throw a local javax.net.ssl.SSLException. A fatal-level alert will no longer be sent to the peer, and the underlying session will remain valid.

In addition, the internal transport context for the SSLSocket will also now be closed. Previously, this step didn't occur if a fatal message was generated.
