Java 8 Update 162 javax.net.ssl.sslexception received fatal alert unexpected_message


(I am not a Java expert but if you can provide instruction and where I need to run commands or make changes I should be fine thanks again)

We have a https client that connects to a webservice over ssl. This always works fine with Java 7. We are upgrading computer to Java 8 Update 162. Unfortunately the client is no longer able to connect to the webservice. I want to know what is causing this and how to fix it?

And the client throws the following exception:

Solution

  • Apologies for the delay so I followed your advice Karol Dowbecki Java update 31 disables SSLv3 so installed Java update 25 and this fixed the issue and all the applications worked fine onn the closed network.

    I do understand the SSL will need upgrading to TLS on the application side but I have no control on this as its supported by a different team.
