Code

public function getInstance(Constraint $constraint) {
    $class_name = $constraint->validatedBy();
    // Constraint validator instances should always be initialized newly and
    // never shared, because the current validation context is getting injected
    // into them through setter injection and in a case of a recursive
    // validation where a validator triggers a validation chain leading to the
    // same validator the context of the first call would be exchanged with the
    // one of the subsequent validation chain.
