All Implemented Interfaces and Traits:

jakarta.validation.ConstraintValidator<NotEmptyWhenNullableConstraint, Map>

@CompileStatic
class NotEmptyWhenNullableConstraintForMapValidator
extends Object
implements jakarta.validation.ConstraintValidator<NotEmptyWhenNullableConstraint, Map>

Validates if Map is empty.

Null Maps are ignored (reported as valid).

This constraint validator is very similar to the standard bean validation's NotEmpty, but this one skips null Maps and does not report them as violations.
