Ehh, I think the wording was not very good. What I meant is after some JDK changes are put back we will remove some unused code from the VM and that VM (which will be >= HS23) cannot be dropped into 7 GA or 7u2. But of course it's possible to use this VM in >= 7u4. I hope that makes it more clear.
The reason I posted this heads-up here is that there might be a timeframe in the future were people are building the latest VM from hotspot-comp and want to drop that into 7 GA. -- Chris On Oct 15, 2011, at 12:13 AM, Paul Hohensee wrote: > Umm, "make it impossible to drop HS23 into JDK7"? > That'd be a no-no. > > Paul > > Sent from my iPhone > > On Oct 14, 2011, at 6:33 AM, Christian Thalinger > <christian.thalin...@oracle.com> wrote: > >> >> On Oct 14, 2011, at 11:23 AM, Christian Thalinger wrote: >> >>> >>> On Oct 14, 2011, at 9:43 AM, Ola Bini wrote: >>> >>>> Hi, >>>> >>>> I'm finally about to get back to hacking on Seph, specifically looking >>>> at performance - I would really like to be able to run the latest >>>> changes (things for u2 related to invoke dynamic) in MacOS X - what is >>>> the current status of this, and is it even possible at the moment? >>> >>> Daniel Dougherty is currently working on getting the Mac OS X changes into >>> HS23 (the runtime repository to be precise).
