Berkeley DB Java Edition 3.3.82

Berkeley DB Java Edition 3.3.82 is a patch release consisting of fixes for a number \
of significant issues. We strongly recommend that users of the 3.3.x version upgrade \
to this release. 

There are several issues that are critical for applications using deferred write (aka \
temporary databases), XA, the shared environment cache, a single transaction in \
multiple threads, or large sets of duplicates.

These critical fixes are below:

* Fix a bug that could cause a LogFileNotFoundException when using an XAEnvironment, \
if a prepared transaction is not ended prior to a crash and then the prepared \
transaction is aborted after recovering from a crash. [#17022] (3.3.79) 

* Fix a bug that prevented deferred-write record deletions from being made durable by \
Database.sync, if a crash occurs after Database.sync but prior to the next \
checkpoint. Under rare circumstances this could also result in a \
LogFileNotFoundException later when accessing the deleted entry. [#16864] (3.3.78) 

* Fix a bug that prevents log cleaning from functioning properly when a temporary DB \
(DatabaseConfig.setTemporary) is large enough to overflow the JE cache. Also fix a \
bug that could in rare cirumstances cause an endless loop while performing log \
cleaning. [#16928] (3.3.78) 

* Fix a bug that caused an infinite loop under certain timing dependent circumstances \
when using EnvironmentConfig.setSharedCache(true). This bug was reported in two \
different forum posts (http://forums.oracle.com/forums/thread.jspa?threadID=832695 & \
http://forums.oracle.com/forums/thread.jspa?messageID=3275138). [#16882] (3.3.78) 

* Fix a bug that caused NullPointerException when opening an XAEnvironment under \
certain circumstances, when prepared but uncommitted transactions are present in the \
JE log and must be replayed during recovery. [#16774] (3.3.77) 

* Fix a bug that caused LogFileNotFoundException in rare circumstances for an \
Environment having one or more Databases configured for duplicates (or one or more \
SecondaryIndexes with MANY_TO_XXX relationships). The bug only occurs when a single \
secondary/duplicate key value is associated with a large number of records/entities; \
specifically, the sub-Btree for a single duplicate key value must have at least 3 \
levels. [#16712] (3.3.76) 

* Fix a bug that caused BufferOverflowException while writing transactional records. \
This could occur if multiple threads were writing to an environment while using the \
same Transaction. [#17204]
