Some APM-Tools support monitoring JPA queries.
Some of them do this in a JPA-vendor-neutral way by using toString() to identify the CriteriaQuery.

Hibernate currently just gives e.g.:
org.hibernate.jpa.ciretia.CriteriaQueryImpl@1b123asdf)

A nice string representation maybe of the JPQL string or string representations of all nodes in the Query-AST or something completely would be nice.
Not only for APM but also for debugging
