Some Java needs to import TLS certificate to Java KeyStore by keytool. Otherwise you get the below error.
Could be linux distribution problem.

1. Maybe Broker Java doesn't have permission to read the Trusted Root Certificate
in Centos directory you imported the certificate.
2. Maybe Java doesn't have Parameter to read it from Trusted Root Certificate.
javax.net.ssl.trustStoreType
3. Maybe we have to let the Java to add the certificate on their own system
by keytool
<keetool commands>
keytool -import -trustcacerts -keystore $JAVA_HOME/lib/security/cacerts -storepass changeit -noprompt -alias mycert -file my-cert.pem
Only crt and cer, pem can be imported. Not pfx. You can convert pfx to crt.
