------------------------------------------------------------------
Reproducer attached. Needs Java 17 bc of Jetty 12.
To run with Mojarra:
{noformat}
mvn jetty:run -Pmojarra40{noformat}
for MyFaces:
{noformat}
mvn jetty:run -Pmyfaces40{noformat}
Seems like MyFaces can't find the validator if the value attribute isn's
specified:
{code:java}
@FacesValidator(managed = true)
public class MyCdiValidator implements Validator {{code}
according to the specs it should default to class.getSimpleName()

> I'm moving one application from Mojarra to MyFaces.
> One of the page fails on submit because of a NullPointerException in
> FacesValidatorCDIWrapper.
> Debugging I found out it happens on a validator attached to a composite
> component using the for attribute.
> I'll try to arrange a standalone reproducer, meanwhile here's the stack trace:
> {code:java}
> java.lang.NullPointerException: null
