The RLSClient accepts null parameters and passes them to the RLS JNI calls. 
The JNI calls invoke JDK JNI library routines without checking for null 
parameters. It appears that the JNI lib routines crash when passed null 
parameters.

We need to check for null parameters, preferably in the Java portion of the 
RLSClient, and throw exceptions rather than passing through to the JNI portion 
of the code.
