Have you looked at restricted vs unrestricted JCE SSL JVM capabilities?

If you ever get around to finding the SSL trace file, it will provide more information on the available ciphers being negotiated.

Hint: The error message you are quoting is NOT the SSL trace.

/var/mqsi/components/<broker_name>/<execution_group_long-hex-uuid>

The easiest way to get the hex UUID is to look for the process for this execution group.

Hi There,

Thanks a lot for your suggestions.

We have found out the cause. We were using certificate which was having RC4 cypher and In java.security we are blocking this cypher.

jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768

hence it was not working.
