Thanks Alex. I was able to verify the issue by adding the rt file from the jre and it did not throw exceptions.

Seems netty/casandra driver expect the javax.security.cert.X509Certificate to be readily available which it is for normal standalone java clients but it is not for the server side. That class is in the rt.jar for the jre. But since the server side does not use the rt.jar it is not found. Some recent change in netty or the datastax driver expects the class but it can not be found on the server side. I hate to use the client side rt.jar with all the javax classes but that is what is needed. I suspect the datastax testing did not take this into account? I am using cassandra driver with the Wildfly J2EE container so I am using the driver in that configuration not a standalone client. That by the way worked fine when I was testing some CQL through the driver.

I was using netty-3.0.9.0.Final with Cassandra driver cassandra-driver-core-3.0.2.jar and netty-handler-4.0.33.jar. So what is the right combination to not get this timer class missing exception? Thanks.

If I get the latest netty-alll-4.0.46.Final.jar during runtime I get an exception about not having a java.security.cert.x509Certificate class. So what to do?
