[jbpm-dev] Support for Hibernate 4 and JPA2

[Marco Rietveld]

Hi Ove!

I did some work on this early this year -- thanks very much for your 
pull request, it made my work a lot easier.

We've done the following in the past year:

- changed jbpm-persistence-jpa so that the hibernate 3.3 dependency is 
no longer hard-coded into the code, so to speak
- I know that Mauricio corrected some queries in human-task that weren't 
JPA 2 compliant.
- added a "hibernate-4" maven profile that you can compile using 
hibernate 4/JPA 2.

I might have done one or two other things for this, but I can't remember 
them any more  -- which means they also weren't of any consequence.

Regardless, see 
http://mriet.wordpress.com/2012/04/03/jpa-2-with-drools-and-jbpm/
Ignore the second part (¨Developer bits and ranting"), I just reread it 
and had trouble following it myself.. :/

When I initially did all of this work, there were 2 or 3 problems in 
various modules -- code that worked under hib 3.3/jpa 1 but not hib 
4/jpa 2. Unfortunately, while one or two might have been fixed 
(human-task queries), I think that there are probably one or two still 
left -- these were problems that I was at a loss to explain/fix at the 
time.


Thanks,
Marco
