Class HibernateValidatorClockProviderSystemZoneIdHolder

java.lang.Object
io.quarkus.hibernate.validator.runtime.clockprovider.HibernateValidatorClockProviderSystemZoneIdHolder
class HibernateValidatorClockProviderSystemZoneIdHolder extends Object
A helper class holding a system timezone.

It is reloaded at runtime to provide the runtime-system time zone to the constraints based on a ClockProvider.

Note, that we do not hold the timezone constant in the clock provider itself as we need to "reinitialize" this class, so that the timezone is set to the actual runtime-system-timezone. Having a constant in the clock provider and asking to reload the provider class leads to native build failure:

Error: An object of type 'io.quarkus.hibernate.validator.runtime.clockprovider.HibernateValidatorClockProvider' was found in the image heap. This type, however, is marked for initialization at image run time for the following reason: classes are initialized at run time by default. This is not allowed for correctness reasons: All objects that are stored in the image heap must be initialized at build time.

And we do have instances of the clock provider/clock in the Hibernate Validator metadata as we eagerly initialize constraints.
