Subject Re: Java 7 support?

I am using the Sun JDK. There are only two issues I have found
unrelated to Cassandra.

1) DateFormat is more liberal yyyymmDD vs yyymmdd If you write an
application with java 7 the format is forgiving with DD vs dd. Yet if
you deploy that application to some JDK 1.6 jvms it fails

2) Ran into some issues with timsort()

Again neither of these manifested in cassandra but did manifest with
other applications.
