Hi Nicolas, Thanks very much for your work on this. I don't have time to process this today, but I hope to soon.
I'm secretly hoping that I'll get the binary packaging issues and distro issues sorted out, and finish all documentation updates in the next week or so. Then I can release 0.15 officially. From then on, I want to make monthly releases, and keep the tree in a releasable state at all times. So I may wait until after the release to fully incorporate your patches. August may be JDWP month. :-) Also, the patches are really big... I don't mind the odd huge patch, but some mailing list subscribers might not like it if it happens too often. We can use this patch as "starting point 0" if you like, and you can post patches against this to reduce the size. Or, you could create a git fork on repo.or.cz and post everything there. Either one is fine with me. Thanks! - Chris On Thu, Jul 30, 2009 at 06:35:43PM +0200, Nicolas wrote: > Hi, > > I have worked about JDWP implementation with Barry. > > At first, you have to apply the patch on GIT barry source in attachment. > > Then, after re-build barry.
