Error description

  • When two users deploy different applications on the same cell
    using the administration console from different locations at
    different times, the other user gets the message to discard
    the changes of the other user before proceeding.
    
    Save conflict gets detected in administration console due to
    modified files in the workspace not being saved to the master
    repository.
    As a result a ConcurrentModificationException is thrown from the
    security MergeManager code.
