Version 8.0.11 is the first General Availability release of the 8.0 series of MySQL Connector/J. It is suitable for use with MySQL Server versions 8.0, 5.7, 5.6, and 5.5. It supports the Java Database Connectivity (JDBC) 4.2 API, and implements the X DevAPI.
X DevAPI: The locking options
lockExclusive(), available when retrieving data from
table.select(), now also accept an optional locking contention value, which is exposed though the enumeration
Statement.LockContention. The combinations of
Statement.LockContention.SKIP_LOCKEDmap directly to the SQL statement
SELECT ... FOR SHAREor
SELECT ... FOR UPDATEwith the SQL option
SKIP LOCKED, for the different InnoDB locking read modes.
X DevAPI: Connector/J now supports the new server-side document ID generation feature. Client-side document ID generation is no longer supported. As a result, the methods
getDocumentIds()have been removed and the method
getGeneratedIds()has been added to the
X DevAPI: The
SHA256_MEMORYauthentication mechanism is now supported by Connector/J for connections using the X Protocol. See the entry for the connection property
xdevapi.authin Configuration Properties for details.
Connector/J now recognizes the data type
GEOMCOLLECTION, which has been introduced in MySQL 8.0.11 as an alias and preferred name to the previously known
GEOMETRYCOLLECTIONdata type. (Bug #27678308)
The lower bound for the connection property
packetDebugBufferSizehas been changed to 1, to avoid the connection errors that occur when the value is set to 0. (Bug #26819691)
Connector/J now supports the use of a custom
SSLSocketFactoryfor returning a custom-constructed SSL socket at the time of connection establishment. (Bug #26092824, Bug #86278)
The source directory and Java package layouts of Connector/J have been revised to make it easier to use custom protocols, APIs, value decoders, and value factories with Connector/J. See the Connector/J source code and the MySQL Connector/J X DevAPI Reference for more details.
When an integer value in a JSON document is modified, it becomes a a
DOUBLEvalue to the MySQL server, which is returned with a decimal when fetched from the JSON document. Therefore, calling
getInteger()upon the changed value with Connector/J resulted in an
NumberFormatException. With this fix,
getInteger()parses such a value correctly and returns an integer. (Bug #27226293)
In the Ant build file
com.mysql.cj.api.confwas missing in the list of OSGi exported packages, causing missing dependencies in OSGi bundles that use Connector/J. (Bug #25765250, Bug #85566)
Name change of the
com.mysql.cj.api.io.SocketFactorycaused backward incompatibility for older Connector/J applications. The old interface has now been reimplemented to avoid the incompatibility. (Bug #25223137, Bug #84099)
