Git clone fails on slave if master is Java 6, slave is Java 6 or 7 and wildcard in branch name

      Java 1.7

      I have Jenkins running on a Linux machine as master, and a slave on the same machine. Git clone's fail on the slave, but work on master. Running Java 1.6 on the master and Java 1.7 on the slave.

      I've restarted the slave, and upgraded to the latest git-plugin.

      Exception on slave is:

      I seems like the root cause is:

      Caused by: java.lang.UnsupportedClassVersionError: org/eclipse/jgit/util/Java7FSFactory : Unsupported major.minor version 51.0

      Why does this happen on a slave, and not on a master node? Does your plugin support Java 1.7?
