Subject Re: State of Cassandra and Java 7
Date Mon, 17 Dec 2012 15:33:07 GMT
I was using jre-7u9-linux-x64  which was the latest at the time.

I'll confess that I did not file any bugs...at the time the advice from
both the Cassandra and Zookeeper lists was to stay away from Java 7 (and my
boss had had enough of my reporting that "*the problem was Java 7"* for me
to spend a lot more time getting the details).
