MQRC_UNSUPPORTED_CIPHER_SUITE error while connecting to IBM MQ from Red Hat Fuse 6.3.

Issue

• We have our Integration environment on 6.3.0 R17 version and it is a 3 fabric ensemble environment. Recently we have updated Java version to openjdk version "1.8.0_275". We have an application/service from where we try to send messages to Border authorities using IBM MQ config. When we(client) try to send messages to Border Authority(server) we are getting attached exception.

• When we have checked with our Network engineers , they informed that they don't see any traffic crossing our firewall when we try to send messages using our application and when we do a telnet to Border authority, the traffic is crossing firewall.
