[hibernate-dev] envers + classic QueryTranslator failing test

I'm working on https://hibernate.atlassian.net/browse/HHH-9996 and I stumbled across the following test: org.hibernate.envers.test.integration.basic.ClassicQueryTranslatorFactoryTest I run the test not only with Derby but also with PostgreSQL and the test fails for both. The query: select e__ from org.hibernate.envers.test.entities.IntTestEntity_AUD e__ where e__.originalId.REV.id = (select max(e2__.originalId.REV.id) from org.hibernate.envers.test.entities.IntTestEntity_AUD e2__ where e2__. originalId.REV.id <= :revision and e__.originalId.id = e2__.originalId.id) and e__.REVTYPE <> :_p0 and e__.originalId.id = :_p1 causes the error java.sql.SQLException: An attempt was made to put a data value of type 'byte[]' into a data value of type 'SMALLINT'. in Derby while in PostgreSQL the error is org.postgresql.util.PSQLException: ERROR: operator does not exist: smallint <> bytea Hint: No operator matches the given name and argument type(s). The problem is related with org.hibernate.hql.internal.classic.QueryTranslatorImpl$ParameterTranslations#getNamedParameterExpectedType(String name) returning null for the _p0 parameter (while the correct return type should be ReivsionTyptType) this cause the wrong sql bind.. Any help is more than welcome? Thanks Andrea
