Berkeley DB Java Edition 5.0.97 update contains several enhancements as 
well as a number of important bug fixes.  All changes are described in 
the change log.  We recommend that anyone using JE 5 upgrade to 5.0.97.  
The enhancements include:

  * A performance enhancement was made to improve multi-threaded write
    performance. The checksum computation was moved out of the critical
    section during which a global mutex is held. This, together with
    earlier improvements to the write path, improve write performance
    overall for multi-threaded applications. However, the performance
    improvements are limited to standalone JE applications; performance
    is not improved for HA applications. [#16925] (5.0.97)
  * In an HA application, the probability of hard rollbacks during a
    master transfer operation has been reduced. [#22658] (5.0.85)
  * Shutdown HA feeder threads and the replica thread promptly as a
    result of an EnvironmentFailureException instead of waiting for the
    environment handle to be closed. The change makes for faster, more
    robust failover and reduces dependence on application behavior.
    [#22637] (5.0.86)
  * Added the EnvironmentConfig.CLEANER_ADJUST_UTILIZATION boolean
    configuration parameter, to allow disabling of undesired automatic
    adjustments to log utilization. By default, adjustments are enabled,
    and the default behavior has not changed. For more information, see
    the javadoc for this parameter. [#22768] (5.0.88)

See the change log for more details on these enhancements and for 
information on a number of important bug fixes.
