Kicking the tires, free, on Garbage First

Just a note to clarify the terms of
using the Garbage
First collector in Java SE 6u14.
Right now, because its still new-ish and not thoroughly battle tested,
its turned off by default and intended for use to evaluate it. As you
know, many
people already have been doing so. Here's the command line option
to turn it on:

   -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC

Once the team has ironed out all the kinks (and please, let them know
if you find any !), it will be ready for primetime, and will be in JDK7,
where it will be available for free, no strings, under the usual terms
as part of the JDK.

The Janitor is told
that an earlier version of the release notes
implied that you had to have a support contract to use G1. Some certainly ran
with that ball and even made a topical story out of it !

Our bad. So we made the notes clearer,
because you don't need to do anything special to try it out. Unless you
want your kinks fixed before everyone else gets the fixes either in the
next update or in JDK 7. In which case, there is nice
little program waiting just for you :)
