      Description

      Hey community,

      after the last upgrade (I guess it was from Jenkins 1.551) to Jenkins 1.584 we encounter serious problems with our legacy Java5 Maven builds.
      When Jenkins calls the Maven plugin (right after "Parsing poms") the build crashes with the following stacktrace:

      I figured out that the only difference between succeeding and failing builds was the version of remoting.jar. The new Jenkins version ships with version 2.46. When I stopped Tomcat and exchanged the remoting-2.46.jar with remoting-2.44.jar the builds work again.

      Could you please investigate this as it is crucial to us that the Java5 builds are still stable to build?

      Thanks!
