Clustering interoperability issues between JDK versions

Solution Unverified - Updated -

Issue

Can the JBoss instances participating in a cluster run on different Java version (major/minor)? Say in future we decide to upgrade Java version, we would like to do so with minimum down time. Is there any difference in upgrading java minor version (say from 1.7.0_40 to 1.7.0_45) than major version (say 1.6 to 1.7)?
