I'm not following properly.....

MultiTableEntityPersister produces some SQL with "left outer join"
hardcoded, as you noted. Some refactoring is needed to fix this. But I'm
pretty sure the SQL generation for outerjoin fetching never produces "LEFT
OUTER JOIN" when the SQL dialect is set for Oracle. Surely you aren't seeing
this when using EntityPersister?

The reason Hibernate is safe for use in a cluster is that by default caching
is done at the transaction-level. We do not support the use of
cross-transaction caching in a clustered environment, though Christian
Muenier might be releasing some code for this is a seperate project.
