Hi, I'd like to propose to change Class.checkInitted() to check if the VM initialization has completed by using sun.misc.VM.isBooted() instead of System.out != null.
The current check needlessly triggers System class initialization (thus complicating bootstrap initialization order on VMs that don't have a strict initialization bootstrap) and is also not strictly correct, because System.out == null is a valid state after initialization has completed. Thanks, Jeroen
