   I'm getting an error when trying to send a Gremlin script with double-quoted strings (GStrings) to JanusGraph: 
   
   ```
   org.apache.tinkerpop.gremlin.driver.ser.SerializationException: java.lang.IllegalArgumentException: Class is not registered: org.codehaus.groovy.runtime.GStringImpl
   Note: To register this class use: kryo.register(org.codehaus.groovy.runtime.GStringImpl.class);
   ```
   
   We should probably register this automatically? Otherwise the user would have to point at the class and JAR just to use normal Groovy objects.
