Hello, I have an entity MyEntity with a collection attribute myCollection. I have an EntityListener on MyEntity with a @PostUpdate method. When I try to access myCollection from the PostUpdate method, this collection is null . If I try to access the collection from the PreUpdate method

We are testing objectDB with a multi thread application. Each thread has it's own entityManager created from a common factory. In one thread we receive sometimes an object from the database with the field that is declared as @Id having the value null (what is not correct, we checked

we have the critical problem that we receive a null or by zero (in the log a java.lang.ArithmeticException) error for this query: select o from ObjectNode o where o.currentLocation.nodePath = "/(MG)TOOLPOOL-DMC-125U4/(MP)IN" and o.classIdentifier = '(TP)' database can be download from

Objectdb ignores not null annotations
