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() http://stackoverflow.com/questions/6626437/why-does-my-compare-method-throw-exception-comparison-method-violates-its-gen Again neither of these manifested in cassandra but did manifest with other applications.
