When you have two tables a,b
where b has a fk-constraint on a.field,
dropping table a before table b fails.

JBossCMP unfortunately does not take those fk
constraints into account when dropping EntityBeans/Tables.
So when the container first drops b, everything is ok,
but if it first tries to drop a, this fails while b
will be dropped afterwards.
