I'm configuring the builds to use Maven toolchains, as the other approaches require changing all builds to freestyle projects, and apart from the amount of work required to do that, I'm not sure we would lose some nice features the maven plugin has.
I've configured a toolchain file using the Config file Provider Plugin [1] that defines the Oracle JDK 1.7 (the one we use by default in all builds). We can add there other JDKs as we need them. I've also created a PR to configure the maven-toolchains-plugin in a "jenkins" profile, so it is only used in our CI builds. To use that, we'll have to modify all the builds to include the "jenkins" profile, and to use the defined toolchains.xml file. I've done that for the jclouds-pull-requests build, and will copy that to all other builds, if there is no one against this approach, once it succeeds.
