Compatibility With Java11

[Umang Singh]

Hi,

I see there was a fix which would enable Cassandra-Unit to be compatible with Java 11 but couldnt find any progress on that(PR was raised).

The context to this is i am in the process of upgrading Java to 11 from 8 and the UTs are failing with the below exception.

Enter code here...ava.lang.ExceptionInInitializerError
