[bv-dev] [Java 8] How about support java.time in @Future and @Past?

[Gunnar Morling]

As Hardy said, these new data types should be supported in the next BV
revision. HV-825 is our testing bed for bringing the new functionalities
from Java 8 to the world of Bean Validation; If you have any ideas around
this make sure to let us know.

Related to that, I think it should be simpler to add additional constraints
in a "global" manner than it is today. One possible way would be to support
registering validator implementations using the service loader SPI, by
providing a file META-INF/services/javax.validation.ConstraintValidator
which lists additional implementations. This avoids the XML and allows to
add a JAR with validators to an application without further need for
registration.
