> Daemon Thread [ref handler] (Running)
> Daemon Thread [finalizer] (Running)
> Daemon Thread [finalizer] (Running)
> Daemon Thread [finalizer] (Running)

> Daemon Thread [finalizer] (Running)
> Daemon Thread [finalizer] (Running)
> Daemon Thread [finalizer] (Running)
> Daemon Thread [finalizer] (Running)
> Daemon Thread [finalizer] (Running)
> With GCv41 (using -XX:vm.dlls=gc_cc.dll):
> HelloWorld [Java Application]
> HelloWorld at localhost:1045
> Thread Group [system]
> Daemon System Thread [FinalizerThread] (Running)
> Thread Group [main]
> Thread [main] (Suspended (breakpoint at line 5 in HelloWorld))
