e.g. from https://builds.apache.org/job/PreCommit-HBASE-Build/8107/console : /home/jenkins/tools/java/latest java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) Server VM (build 20.1-b02, mixed mode) On Tue, Dec 10, 2013 at 8:06 AM, Enis Söztutar <enis....@gmail.com> wrote: > +1 on changing the defaults, but it seems we should be at least building > with JDK6. > > Enis > > > On Mon, Dec 9, 2013 at 2:55 PM, lars hofhansl <la...@apache.org> wrote: > > > Maybe for 0.94 we should do both after all. > > There will be installations out there with JDK 6 and we should make sure > > we do not break anything there. > > > > I'll set up an additional full build for 0.94 based on JDK 7. > > > > -- Lars > > > > > > > > ________________________________ > > From: Jean-Marc Spaggiari <jean-m...@spaggiari.org> > > To: dev <dev@hbase.apache.org>; lars hofhansl <la...@apache.org> > > Sent: Monday, December 9, 2013 4:01 AM > > Subject: Re: Default JDK settings for Jenkins projects > > > > > > So if we move 0.94 in JDK 7, I guess we all agree there is no reason to > > keep trunk in JDK 6, right?
