particular parameter if required. Let's explore a few examples:
 <pre>
 //Cross-parameter constraint on method
 //createUser(String password, String passwordRepeat)
 //Build a constraint violation on the default path + "passwordRepeat"
 context.buildConstraintViolationWithTemplate("Passwords do not match")
             .addParameterNode(1)
             .addConstraintViolation();

 //Cross-parameter constraint on a method
 //mergeAddresses(Map&lt;String,Address&gt; addresses,
 //        Map&lt;String,Address
