Java 7 support?
Hi all,
The Datastax documentation says that Java 7 is not recommended[1].
However, Java 6 is due to EOL in Feb 2013 so what is the reasoning
behind that comment?
Is it something we should be still concerned about?
Cheers,
Edward

FWIW, we're using openjdk7 on most of our clusters. For those where we
are still on openjdk6, it's not because of an issue - just haven't
gotten to rolling out the upgrade yet.
We haven't had any issues that I recall with upgrading the JDK.

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.

Are you using openJDK or Oracle JDK? I know java7 should be based on
openJDK since 7, but still not sure.

We have been using cassandra and java7 for months. No problems. A key
concept of java is portable binaries. There are sometimes wrinkles with
upgrades. If you hit one undo the upgrade and restart.

Umm, no? Care to explain?

And if you want a competitive edge, use it, tune it, take full advantage of the better version (7) and DON'T share. See the problem with not assigning this as a first class task for ASF team?

That sounds about right. The best way to change the status quo would
be to use Java 7, report any bugs you find, and share your
experiences.

I've asked this approximate question here a few times, with no
official response. The reason I ask is that in addition to Java 7 not
being recommended, in Java 7 OpenJDK becomes the "reference" JVM, and
OpenJDK is also not recommended.
