> Mina's {{SslFilter}} wraps Mina's {{SslHandler}}, which itself wraps Java's 
> {{SSLEngine}}.
> {{SslFilter}} does not catch runtime exceptions that are thrown by 
> {{SSLEngine}} - I am unsure if this is by design.
> Ideally, we'd prevent the engine to get into a state where it can throw such 
> exceptions, but I'm not sure if that's completely feasible.
> None-the-less, I'm here providing an improvement that prevents at least one 
> occurrence of an unchecked exception from being thrown (instead, my patch 
> preemptively throws an {{SSLException}} that is then caught by the exception 
> handling that's already in place).
> An alternative to this fix could be an additional catch block, that handles 
> unchecked exceptions.
> The scenario that is causing the unchecked exception that is caught by this 
> patch, is this:
> * client connects, causes an SslFilter to be initialized, which causes the 
> SSLEngine to begin its handshake
> * server shuts down the input (for instance, for inactivity, or as a 
> side-effect of resource starvation)
> * client sends data
> The corresponding stack trace starts with this:
> {code}java.lang.IllegalStateException: Internal error
>         at 
> sun.security.ssl.SSLEngineImpl.initHandshaker(SSLEngineImpl.java:470)
>         at sun.security.ssl.SSLEngineImpl.readRecord(SSLEngineImpl.java:1007)
>         at 
> sun.security.ssl.SSLEngineImpl.readNetRecord(SSLEngineImpl.java:907)
>         at sun.security.ssl.SSLEngineImpl.unwrap(SSLEngineImpl.java:781)
>         at javax.net.ssl.SSLEngine.unwrap(SSLEngine.java:624){code}
> Inspiration for this fix was obtain from the Jetty project, notably, this 
> change: https://github.com/eclipse/jetty.project/issues/1228
