Here are a few more facts that might give some clues. Master is running Jenkins 1.609.3 in Oracle JDK 1.6.0_75 Slave is Linux running Oracle JDK 1.8.0_20 Git Plugin version 2.4.0 Git Client version 1.19.6
I modified the job configuration to restrict execution to a different slave (one that it had not run on previously) . Then attempted to build the job manually. Result was a slightly different exception (see stack). The interesting point here is the class version issue from the root cause frame. Caused by: java.lang.UnsupportedClassVersionError: org/eclipse/jgit/util/Java7FSFactory : Unsupported major.minor version 51.0 This suggests that something is compiled with JDK 1.7 and being executed on the master which is JDK 1.6. I'm guessing the git client plugin. Will keep digging.
