the jclouds plugin (ec2, openstack, etc compatible slave launcher) is currently rev-locked to <guava 12, as the project reverted back to guava 11 to ensure JDK5 compatibility. This means the plugin cannot get latest jclouds updates, which employ guava 12 features.

We don't want to be limited to JDK5 libraries forever. How can plugins use modern libraries while this restriction is in place? Is there another build we can make for JDK6+ only?
