Dear MySQL users,

MySQL Connector/J 5.1.33, a maintenance release of the production 5.1
branch has been released. Connector/J is the Type-IV pure-Java JDBC
driver for MySQL.

Version 5.1.33 is a maintenance release of the production 5.1 branch.
It is suitable for use with MySQL server versions 5.5 and 5.6.

MySQL Connector Java is available in source and binary form from the
Connector/J download pages at
http://dev.mysql.com/downloads/connector/j/5.1.html

MySQL Connector Java (Commercial) is already available for download
on the My Oracle Support (MOS) website. This release will be available
on eDelivery (OSDC) in next month's upload cycle.

As always, we recommend that you check the "CHANGES" file in the
download archive to be aware of changes in behavior that might affect
your application.

MySQL Connector/J 5.1.33 includes the following general bug fixes and
improvements, also available in more detail on
http://dev.mysql.com/doc/relnotes/connector-j/en/news-5-1-33.html :


Changes in MySQL Connector/J 5.1.33 (2014-09-25)


Bugs Fixed

* Many parameters specified with options when making an Ant
build of Connector/J from source (for example,
com.mysql.jdbc.testsuite.url.sha256default) were not set as
system properties and thus were not available for use in the
JUnit tests in the testsuite. With this fix, all
com.mysql.jdbc.test.* and com.mysql.jdbc.testsuite.*
parameters are forwarded to the JUnit tests. (Bug #19505524)

* XA connections failed with a class cast exception for a
load-balanced configuration with
pinGlobalTxToPhysicalConnection=true. This was because some
XA-related classes used com.mysql.jdbc.ConnectionImpl in
method parameters during calls. This fix makes the classes use
com.mysql.jdbc.Connection instead in those cases. (Bug
#19450418, Bug #73594)

* The 4-byte UTF8 (utfbmb4) character encoding could not be used
with Connector/J when the server collation was set to anything
other than the default value (utf8mb4_general_ci). This fix
makes Connector/J detect and set the proper character mapping
for any utfmb4 collation. (Bug #19479242, Bug #73663)

* changeUser() calls might result in a connection exception
("Got packets out of order") or a freeze if the useCompression
option was set to true. (Bug #19354014, Bug #19443777, Bug
#73577)

* The MANIFEST.MF file for the JAR package of Connector/J
included an empty line between the attributes Import-Package
and Name, which was interpreted as a mark for the end of the
main section of the manifest file. This fix removes the empty
line. (Bug #19365473, Bug #73474)

* The tests testByteStreamInsert and testUseCompress in the
Connector/J testsuite failed with the message "Row size too
large (> 8126)..." when they were run against the MySQL server
version 5.6.20. This is due to a known limitation with the
server version, for which innodb_log_file_size has to be set
to a value greater than 10 times the largest BLOB data size
found in the rows of the tables plus the length of other
variable length fields (that is, VARCHAR, VARBINARY, and TEXT
type fields) (see the MySQL 5.6.20 changelog
(http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-21.ht
<http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-21.html>
ml <http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-21.html>)
for details). This fix adds, for MySQL 5.6.20, a check for
innodb_log_file_size to assert that its value is 335544320 or
larger and throws an exception if it is not so, asking the
user to increase the size of innodb_log_file_size. (Bug
#19172037)

* Using Java 6 or later, running LOAD DATA INFILE with a
prepared statement resulted in an IndexOutOfBoundsException.
This was a regression introduced by an issue in the patch for
Bug #72008, which has now been fixed. (Bug #19171665, Bug
#73163)

* Connector/J failed the test for Bug# 64205 in the testsuite,
thus might return a garbled error message for an invalid query
when connected to MySQL server 5.5 or later. The failure was a
regression introduced by the fix for Bug #18836319, which made
the issuing of SET NAMES dependent on the character set
difference between the server and the connection. This fix
corrects the way by which the error messages are interpreted,
so that they will come out right at any stage of a connection.
(Bug #19145408)

* Errors occur when Connector/J mapped Windows time zones to
Olson time zones for "Caucasus Standard Time" and "Georgian
Standard Time". This fix corrected and updated all the
time-zone mappings in Connector/J using the data from the IANA
Time Database and the Unicode Common Locale Data Repository
(CLDR) v.24. (Bug #17527948, Bug #70436)

* The test case testsuite.simple.XATest.testRecover failed when
run against MySQL servers 5.7.0 to 5.7.4, because Connector/J
did not understand the new output format for XA RECVOER that
was introduced since MySQL 5.7.0 for fixing Bug #19505524.
That fix has recently been reverted in MySQL 5.7.5, so that XA
RECOVER output is now, by default, in the old format again.
The test case, which runs well with MySQL 5.7.5, is now
skipped for server versions 5.7.0-5.7.4. (Bug #17441747)
