However, looking at the code on GitHub this is still present on main (as confirmed by Christian). Note that this is not just an issue with a single ValidatorImpl instance used by multiple Threads, but also with each Thread using it's own Validator instance. In particular, the non-thread-safe part in PersistenceUtilHelper is static and will be shared by all instance of ValidatorImpl.
