    *                      ReadOnlyException exceptions when a     *
    *                      client attempts to update any map.      *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When the BackingMap is configured with an evictor and
    CopyMode.COPY_TO_BYTES, there is at least one synchronous
    replica, and the value object (the value being cached) is not
    present in the container server classpath, the replica
    incorrectly attempts to inflate your data object,
    resulting in the ClassNotFoundException exception on the
    replica server, which might manifest in other exceptions to the
    client.
