Those are good suggestions guys. I'm using Java 7 and this is my first install of C* so looks like it might be genuine.

From what I understand this is a minor issue that doesn't affect the functionality, correct? If not I should prob download a prev version of C* or build my own...

Have filed a Jira here:
https://issues.apache.org/jira/browse/CASSANDRA-5253

Thanks
Ahmed

It can also happen if you have an older/non sun jvm.
