In Java 8 there is a new compiler flag that allows additional metadata to be stored with byte code and these parameter names can be extracted using the Parameter object in reflection. See JDK 8 spec. In newer versions of hibernate org.springframework.core.ParameterNameDiscoverer uses this feature. To use it compile using javac with this flag:

-parameters                Generate metadata for reflection on method parameters

Access parameters using reflection's Parameter class.
