Description

When running nodetool cfhistograms on 2.1-HEAD, I am seeing the following exception:

04:02 PM:~/cstar/cassandra[cassandra-2.1*]$ bin/nodetool cfhistograms keyspace1 standard1
objc[58738]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

I can reproduce this with these simple steps:
Start a new C* 2.1-HEAD node
Run cassandra-stress write n=10000
Run nodetool cfhistograms keyspace1 standard1
