Thanks a lot for writing this JIRA task. However it may be worth to 
emphases that clobbering an open JAR file is an hypothesis that may 
explain the JVM crash, but this is unverified. There is some arguments 
that may me think that the problem may be somewhere else:

  * In our case, nothing is touching this JAR file in parallel (there is
    only one Jenkin job building this JAR, and we are not doing parallel
    builds).
  * This snapshot JAR file is used as a plugin for other modules well
    after the build has been completed.
  * The build using JDK6 on the same Jenkin server never crashed.
  * The build using JDK7 on an other (non-Apache) Jenkin server never
    crashed.
  * The build using JDK7 on the Apache Jenkin server never crashed when
    the plugin was executed under the Maven "generate-resources" phase.
    Executing a plugin in the same JAR under the "package" phase cause
    the crash, despite the "package" phase being after the
    "generate-resources" phase.


Maybe the cause of the JVM crash is something cobbling the open JAR 
file, but I think that this is an uncertain hypothesis. I would like 
pretty much to try with an upgraded JDK7 on the Jenkins server first... 
Is there anything we can do for helping for a JDK7 upgrade?

     Thanks,

         Martin
