Here’s an example of a Criteria Query that triggers the problem: Path<LocalTerm> asLocalTerm = cb.treat( root.get( "term" ), LocalTerm.class ); criteria.select( root ).where( cb.equal( asLocalTerm.get( "property" ), value ) ); And here’s the stack trace: java.lang.IllegalArgumentException: Already registered a copy: SqmEntityValuedSimplePath(treat(org.hibernate.orm.test.jpa.criteria.TreatTablePerClassTest$Linkage(27365580293082).term as org.hibernate.orm.test.jpa.criteria.TreatTablePerClassTest$LocalTerm).language) at org.hibernate.query.sqm.tree.SqmCopyContext$1.registerCopy(SqmCopyContext.java:33) at org.hibernate.query.sqm.tree.domain.SqmEntityValuedSimplePath.copy(SqmEntityValuedSimplePath.java:37) at org.hibernate.query.sqm.tree.domain.SqmEntityValuedSimplePath.copy(SqmEntityValuedSimplePath.java:21) at org.hibernate.query.sqm.tree.predicate.SqmComparisonPredicate.copy(SqmComparisonPredicate.java:69) at org.hibernate.query.sqm.tree.predicate.SqmComparisonPredicate.copy(SqmComparisonPredicate.java:20) at org.hibernate.query.sqm.tree.predicate.SqmWhereClause.copy(SqmWhereClause.java:33) at org.hibernate.query.sqm.tree.select.SqmQuerySpec.copy(SqmQuerySpec.java:104) at org.hibernate.query.sqm.tree.select.SqmQuerySpec.copy(SqmQuerySpec.java:53) at org.hibernate.query.sqm.tree.select.SqmSelectStatement.copy(SqmSelectStatement.java:131) at org.hibernate.query.sqm.tree.select.SqmSelectStatement.copy(SqmSelectStatement.java:42) at org.hibernate.query.sqm.internal.QuerySqmImpl.<init>(QuerySqmImpl.java:227) at org.hibernate.internal.AbstractSharedSessionContract.createQuery(AbstractSharedSessionContract.java:1295) at org.hibernate.internal.SessionImpl.createQuery(SessionImpl.java:181) The issue appears to be caused by the copy method of the treatedPath.get("property") object: here, the left-hand side, which is the {{treat}}ed path, causes another copy of the property to be triggered while the first one was still being processed and not registered.
