+While adding an entity of class %s with an ID hash of "%s" to the identity map,
+another object of class %s was already present for the same ID. This exception
+is a safeguard against an internal inconsistency - IDs should uniquely map to
+entity object instances. This problem may occur if:
+
+- you use application-provided IDs and reuse ID values;
+- database-provided IDs are reassigned after truncating the database without
+clearing the EntityManager;
+- you might have been using EntityManager#getReference() to create a reference
+for a nonexistent ID that was subsequently (by the RDBMS) assigned to another
+entity.
+
+Otherwise, it might be an ORM-internal inconsistency, please report it.
