I was able to run IBM Java 7 with Cassandra (could not do it with 1.6
because of snappy). It has a new Garbage collection policy (called
balanced)  that is good for very large heap size (over 8 GB),
documented <http://www.ibm.com/developerworks/websphere/techjournal/1108_sciampacone/1108_sciampacone.html>
here<http://www.ibm.com/developerworks/websphere/techjournal/1108_sciampacone/1108_sciampacone.html>
that
is so promising with Cassandra. I have not tried it but I like to see how
it is in action.
