Berkeley DB Java Edition 4.1.10 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:

    * [#19567] Fixed a bug that caused a hard deadlock between a thread performing an Environment.sync (or a checkpoint when deferred-write databases are used) and another thread (which could be an application thread) that is performing eviction. The problem occurs when evicting cached information for a database that is no longer in use, and is most likely to occur after closing a database and/or when the JE cache is small enough to cause heavy eviction activity.

    * [#19636] Fixed a bug that caused an infinite loop when calling the Transaction.commit or Transaction.abort method, when the transaction is used to both truncate and remove a single database, using Environment.truncateDatabase and removeDatabase. Now an exception will be thrown by Environment.removeDatabase in this situation, and the application must call Transaction.abort operation to end the txn. Although this is not a final solution (ideally it should be possible to both truncate and remove a database in a single transaction), this fix prevents the infinite loop in the commit and abort methods. Thanks to Christoph for reporting this on OTN.

    * [#19680] Fixed a race condition that sometimes caused Environments opened with EnvironmentConfig.setSharedCache(true) to not use the shared cache and instead use a private cache. This happened only when opening multiple Environments concurrently in more than one thread. Thanks to Tim Underwood for reporting this on OTN and identifying the specific problem in the JE source code.

    * [#19754] Fixed a bug that causes an EnvironmentFailureException when a JE HA environment is restarted. Thanks to Jan for reporting this problem on OTN and working with us to fix it.
