The following bug is targeted for our next major release. Please vote
for it and add comments.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=362707
There are a number of places we get properties that are used to
configure the persistence unit.
1. persistence.xml
2. passed properties
3. System properties
We will have to determine the order of precedence for those properties.
