        Description

        There are two ways in which the performance problem encountered by the
        customer (see display 1 in "Comments" section) can be ameliorated
        via changes/improvements to SoftReference processing within
        the GC subsystem, one of which is specific to concurrent collectors.

        The customer's application has, meanwhile, taken steps at the application
        level to avoid (workaround) this performance problem.

        A simple test case will be attached to this bug, illustrating the problem,
        and will serve to highlight the performance improvement as a result of
        the "Suggested Fix".
