I get an error object already exists when calling em.persist(serviceInstance) method. Object has several OneToMany(unidirectional) child object links, and one of the ServiceInstance -> ServiceInstanceProperty child object has this error.
I put SQL=TRACE logging but this error happens before sql formula is sent to a jdbc driver. Tried to sysout print prop.hashCode() but no match to a ServiceInstanceProperty@4f70aab2 value I can think of.
Is there a way to get more information about this object, hashCode()+key_values+values anything able to match to a property instance? Can I ask OpenJPA to give me @4f70aab2 value of the property instance?

edit1: ok I was able to pinpoint an object by using a primary key BeanProperty$PK@b0709ec6 hashCode-to-hex value, primary key object is "never changed" hashCode value so easier to track object. Now need to study what went wrong in saving a jpa entities.
edit2: my copypaste mistake, updated two objects with the same PK key, secret was to print toHexString(obj.getPK().hashCode()) from the primary key as it's not anything set by an internal OpenJPA id tracking.
