"The monetization of Java has begun. Sun released the Java 1.6.0_14 JDK and JRE today which include a cool new garbage collector called G1. There is just one catch. Even though it is included in the distribution, the
release notes state 'Although G1 is available for use in this release, note that production use of G1 is only permitted where a Java support contract has been purchased.' So the Oracle touch is already taking effect. Will
OpenJDK be doomed to a feature-castrated backwater while all the good stuff goes into the new
Java SE for Business commercial version?"
To try G1, specify these command line options:
-XX:+UnlockExperimentalVMOptions -XX:+UseG1GC
I don't see anything obvious preventing you from using it (no license/support keys?), it's just not recommended since it's
experimental. If you're crazy enough to use it on a production server, you better have a support contract so Sun/Oracle can fix any problems that come along. That seems reasonable.
Although it'd be better if they just said "don't use it for production, period."
