Berkeley DB Java Edition 4.1.20 is a patch release consisting of fixes 
for a number of issues. We strongly recommend that users of the 4.1.x 
version upgrade to this release. These fixes include:

  * [#21348]  Fixed a bug that caused an EnvironmentFailureException
    with LOG_FILE_NOT_FOUND. The bug occurred after deleting a range of
    keys in a deferred-write database
    (DatabaseConfig.setDeferredWrite(true) or
    StoreConfig.setDeferredWrite(true)), closing the Environment, and
    then opening the Environment.
  * [#21304]  Fixed a bug in the DbPreUpgrade_4_1 and
    DbRepPreUpgrade_4_1 utilities that prevented them from working
    properly due to concurrent log cleaning activity while the utility
    is running.
  * [#20816] Fixed a bug that could cause |Environment.removeDatabase|
    or |truncateDatabase| to loop in a "livelock" pattern along with
    active log cleaner threads, where the |removeDatabase| or
    |truncateDatabase| thread is not making forward progress.
  * [#21015] Added additional fixes to prevent looping and long
    operations times for |Environment.removeDatabase| and
    |truncateDatabase|. The additional fixes address long operation
    times due to log cleaning with large file sizes in combination with
    eviction.
  * [#21177] Fixed a bug that sometimes caused a
    ConcurrentModificationException when calling
    Environment.setMutableConfig, when exception listeners were
    previously configured.
