This is my first issue here, so if I forgot to add some information, just ask 
I've tested the following with 1.3.7 and 1.4.2. On 1.3.6, the behaviour is correct.
I have a prepared statement as follows:
INSERT INTO `tableX` (`textA`, `dateB`, `textC`, `longD`, `tinyintE`) VALUES (?, ?, ?, ?, ?) , (?, ?, ?, ?, ?) , (?, ?, ?, ?, ?) , (?, ?, ?, ?, ?) |
And I add the following parameters (with the Java classes between parentheses):
150 (String), 2016-04-23 16:40:20.804 (Timestamp), 1:142:14895 (String), 5528 (Long), 0 (Integer),
|
null, 2016-04-23 16:40:20.804 (Timestamp), 1:102:1712 (String), 5528 (Long), 0 (Integer),
|
null, 2016-04-23 16:40:20.804 (Timestamp), 1:102:1159 (String), 5528 (Long), 0 (Integer),
|
[] (String), 2016-04-23 16:40:20.804 (Timestamp), 1:142:4142 (String), 5528 (Long), 0 (Integer)
|
Nevertheless, I get the following error (in v1.4.2):
org.mariadb.jdbc.internal.util.dao.QueryException: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'NULL , ('2016-04-23 16:40:20.804', '1:102:1712', 5528, 0, NULL) , ('2016-04-23' at line 1

Query is : INSERT INTO `tableX` (`textA`, `dateB`, `textC`, `longD`, `tinyintE`) VALUES ('150', '2016-04-23 16:40:20.804', '1:142:14895', 5528, 0)<null> , ('2016-04-23 16:40:20.804', '1:102:1712', 5528, 0, <null>) , ('2016-04-23 16:40:20.804', '1:102:1159', 5528, 0, '[]') , ('2016-04-23 16:40:20.804', '1:142:4142', 5528, 0, )

I can't completely figure out why (maybe the null value?) but my initial prepared statement gets changed into an invalid one. As I said, I have encountered this error with Connector/J versions 1.3.7 and 1.4.2 in (as it seems) all queries that use this multiple INSERT syntax. In version 1.3.6 it works as it should.
I hope you can fix this, because this is preventing me from upgrading to the latest version.
