Hi,
Your testcase works for me with no errors on OpenJPA/trunk and
Oracle/XE 10.2. (I haven't tried it on OpenJPA 1.2.x yet).
The generated native query you posted does not seem to match the
original JPQL. There are references to the OC1USER table, which does
not correspond to any entity in your test set, nor is it used as a
supporting table.
I'm pasting my generated native query below - it corresponds to the
JPQL in your testcase. With this query, the problem you mention in
COMMENT1 does not occur. For COMMENT3, aliases t0, t1, t2 and t3 are
all in scope by being declared in the outermost FROM.
Here's the generated native query I get (I replaced parameters with 1s
so I could also try it from sql+):
