Cassandra JRE 8 Two JDKs

So I have the following setup for Java on my Mac OSX Mavericks:

$ java -version

java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

When starting Cassandra via: 

$ cassandra

I get this error statement:

    objc[4347]: Class JavaLaunchHelper is implemented in both 
/Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home/bin/java and 
/Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home/jre/lib/libinstrument.dylib. 
One of the two will be used. Which one is undefined.
Fehler: Ausnahme von Agent ausgelöst : java.lang.NullPointerException

What can I do?

The agent NullPointer exception comes up if Cassandra is already running on that node and is unrelated to the Java warning.

Check jps to see if you have a C* process already running.

$ ps auwx | grep cassandra
$ sudo kill <pid>
