Good to see you back., Patrick. 

Metamodel, Criteria etc are work-in-progress. There are "known unknowns" and
surely there are "unknown unknowns" -- and a regular churn of spec API. The
objective measure of their status is the available unit tests. Some existing
applications  have migrated their JPQL queries to strongly-typed version of
Criteria (i.e. based on canonical, instantiated static metamodel classes)
with no major shortcomings or surprises. But I can not comment on the
complexity of these JPQL queries. Currently Criteria is tested against 450
odd unit tests -- out of that roughly 300 would be using strong-typed
You can find the tests in ....openjpa.persistence.criteria.* packages...

Did something specific jump up as "seemingly-in-progress code"?
