SSL Handshake exception - RESTEASY004655

Question

I am trying to figure out why am having this type of exception all over the log file!!!!

Looking on some internet posts, apparently they talk about network interruption !!!

Any clue about such exception ?

Answer 1

It isn't a network interruption (or an invalid / expired SSL cert). What has happened is the remote end has closed the connection in the middle of the SSL connection negotiation. Most likely it is because there is a mismatch between requested and supported protocol versions or crypto algorithms.

You need to turn on debugging messages for the SSL protocol stack; e.g. using -Djavax.net.debug=all. That will give you more information, and from that you can figure out what you need to do to fix the mismatch.
