Suggestion:

{code}
@ReportAsSingleViolation(shortCircuit=true) /* better name? */
@NotNull /* or @NotEmpty, or @Size(min=50)... */
@Constraint(validatedBy=MyValidator)
public @interface MyConstraint {}
{code}

Currently Hibernate Validator invokes MyValidator even if the value is null.  This is wasteful and pointless.  It also makes it hard to compose cheap vs. expensive validations, or prerequisite validations in a reusable way.  I don't believe this is addressed by the recent "OR" composition type addition to HVAL.
