Command for cassandra-stress was
./cassandra-stress write n=100k -transport
truststore=$HOME/IdeaProjects/Lynk/message-service/cassandra.truststore.jks
truststore-password=cassandra
keystore=$HOME/IdeaProjects/Lynk/message-service/cassandra-client.p12
keystore-password=cassandra
The fix was partially wrong. What we did was
!image-2025-12-10-11-24-29-509.png!
It gave NullPointerException.
but it turned out, we have to add another piece of code
!image-2025-12-10-11-25-13-030.png!
we have to initialize cipher suites only if the values was non-null, if it's
null, there will be auto-negotiation.

Should I update the PR with this fix?
