+              commons-dbcp-1.3/1.4 RELEASE NOTES
+
+This release includes new features as well as bug fixes and enhancements. Some bug fixes
change semantics
+(e.g. connection close is now idempotent).  The 1.3 and 1.4 releases of DBCP are built from
the same sources.
+Version 1.4 supports JDBC 4, so requires JDK 1.6.  Version 1.3 supports JDBC 3 and has JDK
1.4 as its minimum
+JDK requirement.  Other than support for the added methods in JDBC 4, there is nothing new
or different in
+DBCP 1.4 vs. DBCP 1.3. Applications running under JDK 1.4-1.5 must use DBCP 1.3.  Applications
running under
+JDK 1.6 may use DBCP 1.4.
+
+Changes since DBCP 1.2.2 include:
+
+New features:
+o  DBCP-204:  Made PoolingConnection pool CallableStatements. When BasicDataSource's 
+        poolPreparedStatements property is true, CallableStatements are now
+        pooled along with PreparedStatements. The maxOpenPreparedStatements
+        property limits the combined number of Callable and Prepared statements
+        that can be in use at a given time. Thanks to Wei Chen. 
+o  DBCP-226:  Added a validationQueryTimeout configuration parameter to BasicDataSource
+        allowing the user to specify a timeout value (in seconds) for connection
+        validation queries. 
+o  DBCP-175:  Added a connectionInitSqls configuration parameter to BasicDataSource
+        allowing the user to specify a collection of SQL statements to execute
+        one time when a physical database connection is first opened. Thanks to Jiri Melichna
and Jerome Lacoste. 
+o  DBCP-228:  Added support for pooling managed connections. Thanks to Dain Sundstrom. 
+o  DBCP-230:  Added BasicManagedDataSource, extending BasicDataSource.
+        Also improved extensibility of BasicDataSource by encapsulating
+        methods to create object pool, connection factory and datasource
+        instance previously embedded in createDataSource. Thanks to Dain Sundstrom. 
+
+Fixed Bugs:
+o  DBCP-303:  Ensure Statement.getGeneratedKeys() works correctly with the CPDS
+        adapter. Thanks to Dave Oxley. 
+o  DBCP-302:  Removed incorrectly advertised ClassNotFoundException from
+        JOCLContentHandler.ConstructorDetails.createObject(). Thanks to Sebastian Bazley.

+o  DBCP-8:  Handle user password changes for InstanceKeyDataSources. 
+o  DBCP-294:  Added PoolableManagedConnection and PoolableManagedConnectionFactory so that
+        pooled managed connections can unregister themselves from transaction registries,
+        avoiding resource leaks. Thanks to Philippe Mouawad. 
+o  PoolableConnectionFactory.makeObject() is no longer synchronized. This
+        provides improved response times when load spikes at the cost of a
+        faster rise in database server load. This change was made as a partial
+        fix for DBCP-212 although it does not fully address that issue. 
+o  DBCP-242:  Reverted DelegatingConnection close to 1.2.2 version to ensure
+        open statements are closed before the underlying connection is closed. 
+o  Add some test cases that were missing from the TestAll test suite. 
+o  DBCP-235:  Refactor DelegatingConnection and ManagedConnection enable overridden
+        equals() and hashcode() to work correctly. 
+o  DBCP-215:  Modified BasicDataSourceFactory to complete initialization of the pool
+        by creating initialSize connections rather than leaving this to lazy
+        initialization when the pool is used. 
+o  DBCP-253:  Eliminated masked _stmt field in descendents of DelegatingStatement. 
+o  DBCP-191:  Modified DBCP sources to support compilation under JDK 1.4-1.6
+        using Ant flags to do conditional compilation. Thanks to Michael Heuer and J. David
Beutel. 
+o  DBCP-272:  Added a static initializer to BasicDatasource that calls
+        DriverManager.getDrivers() to force initialization before we ever do
+        anything that might use Class.forName() to load (and register) a JDBC
+        driver. 
+o  DBCP-4:  Eliminated direct System.out calls in AbandonedTrace. 
+o  DBCP-264:  Modified DelegatingStatment close to clear open batches. 
+o  DBCP-255:  Eliminated unused private "parent" field in AbandonedTrace. 
+o  DBCP-273:  Fixed errors handling boolean-valued Reference properties in 
+        InstanceKeyObjectFactory, DriverAdapterCPDS that were causing 
+        testOnBorrow and poolPreparedStatements properties to be incorrectly
+        set when creating objects from javax.naming.Reference instances. Thanks to Mark Lin.

+o  DBCP-271:  Made private instance fields of AbandonedTrace volatile (parent,
+        createdBy, lastUsed, createdTime) or final (trace). Thanks to Sebastian Bazley. 
+o  DBCP-270:  Narrowed synchronization in AbandonedTrace to resolve an Evictor deadlock.
Thanks to Filip Hanik. 
+o  DBCP-218:  Corrected Javadoc to state that getLoginTimeout and setLoginTimeout are
+        NOT supported by BasicDataSource. 
+o  DBCP-221:  BasicDataSource.close() now permanently marks the data source as closed,
+        and no new connections can be obtained from the data source. At close all
+        idle connections are destroyed and the method returns.  As the remaining
+        active connections are closed, they are destroyed. 
+o  DBCP-241:  Eliminated potential sources of NullPointerExceptions in 
+        PoolingConnection. 
+o  DBCP-216:  Improved error recovery and listener cleanup in 
+        KeyedCPDSConnectionFactory. Substituted calls to destroyObject with
+         _pool.invalidateObject on error to ensure pool active count is
+        decremented on error events. Ensured that events from closed or invalid
+        connections are ignored and listeners are cleaned up. Thanks to Marcos Sanz. 
+o  DBCP-245:  Fixed error in SharedPoolDataSource causing incorrect passwords to be 
+        stored under certain conditions. Thanks to Michael Drechsel. 
+o  DBCP-237:  Added exception handler to ensure that PooledConnections are not
+        orphaned when an exception occurs in setUpDefaults or clearWarnings in 
+        IntanceKeyDataSource.getConnection. Thanks to Oliver Matz. 
+o  DBCP-252:  Made getPool synchronized in PoolableConnectionFactory.
+        Fixes inconsistent synchronization accessing _pool. Thanks to FindBugs. 
+o  DBCP-252:  Fixed inconsistent synchronization on _rollbackAfterValidation,
+        _validationQuery and _pool in CPDSConnectionFactory and 
+        KeyedCPDSConnectionFactory by making the first two volatile and making
+        both getter and setter for _pool synchronized. Thanks to FindBugs. 
+
+Changes:
+o  DBCP-305:  Use an API specific exception for logging abandoned objects to make
+        scanning the logs for these exceptions simpler and to provide a better
+        message that includes the creation time of the abandoned object. Thanks to Christopher
Schultz. 
+o  DBCP-203:  Make the class loader used to load the JDBC driver configurable for the
+        BasicDatasource. Thanks to Mark Grand. 
+o  DBCP-289:  Made XADataSource configurable in BasicManagedDataSource. Thanks to Marc Kannegie├čer.

+o  DBCP-276:  Added connectionProperties property to DriverAdapterCPDS. 
+o  DBCP-265:  Add a DelegatingDatabaseMetaData to track ResultSets returned from
+        DatabaseMetaData objects. 
+o  DBCP-211:  Added Maven 2 pom.xml. Removed a block of code from TestJOCLed that set
+        the Xerces parser manually. This was to support early JDKs. The 1.3
+        version of DBCP requires JDK 1.4+. 
+o  DBCP-233:  Changed behavior to allow Connection, Statement, PreparedStatement,
+        CallableStatement and ResultSet to be closed multiple times. The first
+        time close is called the resource is closed and any subsequent calls
+        have no effect. This behavior is required as per the JavaDocs for these
+        classes. Also added tests for closing all types multiple times and
+        updated any tests that incorrectly assert that a resource can not be
+        closed more then once.  Fixes DBCP-3, DBCP-5, DBCP-23 and DBCP-134. Thanks to Dain
Sundstrom. 
+o  DBCP-11:  Modified PoolingDataSource, PoolingDriver and DelegatingStatement to
+        assure that all returned Statements, PreparedStatements, 
+        CallableStatements and ResultSets are wrapped with a delegating object,
+        which already properly handle the back pointers for Connection and
+        Statement.  Also added tests to to assure that the *same* object used 
+        to create the statement or result set is returned  from either 
+        getConnection() or getStatement(). Thanks to Dain Sundstrom. 
+o  DBCP-143:  SQLNestedException has been deprecated and will be replaced in DBCP 1.4 with
+        SQLException and standard Java exception chaining.
