No value specified for parameter when using MySQL with JPA/Hibernate
I am using memory based HSQL for unit tests.
I am using file based HSQL for development testing.
I have changed my integration tests to using MySQL from file based HSQL.
Final production release will probably use MySQL or Firebird.
(This isn't commercial work, so no Oracle in any stack...)
But when I switched to MySQL, JPA/Hibernate starting complaining about: No value specified for parameter 2. As usual the generic multiple vendor reasons for using JPA/JDBC usually is not true...
Was a bit dumbfounded with this error, but eventually found the solution : http://opensource.atlassian.com/projects/hibernate/browse/HHH-2605.
As it turns out there is a bug in the version of Hibernate that I use.

And this version in the maven repositories was uploaded with wrong transparent dependency to hibernate 3.2.4.ga, which is buggy.
But the quick fix is to change my own dependency management to use version 3.2.6.
Thus this change solved the problem:
Maven causes problems, but also solves problems...
