Should we use G1 GC under Java 8 or wait for Java 9?

Is G1 GC in Java 8 a common production level quality? Is the G1 implementation the latest version of the Java 8 service (almost) identical to the one included in Java 9?

In other words:

  • Is it good to evaluate applications with G1 and switch to G1 under Java 8?
  • Can we expect updates to the G1 releases in Java 8, so that it is at the same level as in Java 9 (when possible)?
  • or is it better to wait for Java 9, since the behavior will be different?
