I've updated the changes to allow it be implementation specific as to whether a warning is printed when attempting to start the same agent a second or subsequent time. I think to sync up with Ron/Alex on this point on whether the description in the JEP needs to say anything on this. 

For now, attempting to start a JVM TI agent that was previously loaded will not print a warning. We could potentially do the same for Java agents.
