Have anyone faced this SSL Exception while calling Primavera Unifier Web Service 20.9?

Hi Team

We have a custom integration using Unifier Webservice and it's running via Java Concurrent program in the EBS runtime of Version 1.7.

While trying to call the unifier webservice we are facing the below error.

      javax.net.ssl.SSLException: Received fatal alert: protocol_version.

As per the suggestion from online via stack-overflow, we tried to pass the below VM arguments

 -Dhttps.protocols="TLSv1,TLSv1.1,TLSv1.2" 

and some other options also tried like SSLv3 but it doesn't work since Java 7 doesn't have the TLS protocol.

We tried in a local system with Java 8 runtime and we are able to access the unifier webservice. But we can't upgrade the EBS Runtime version to Java 8. 

Howdy, Stranger!
