OpenJpaDialect does not support declarative transaction isolation [SPR-12333]

[spring-projects-issues]

Juergen Hoeller opened SPR-12333 and commented

Like with #16924 for EclipseLink and #16559 for Hibernate, we should try to provide a best-effort translation of custom isolation levels onto OpenJPA configuration.

JDBCFetchPlan.setIsolation seems to be the only thing we can do - which only controls the structure of select clauses but that seems to be exactly what OpenJPA intends.
