All Implemented Interfaces:

ParameterNameProvider

public class ReflectionParameterNameProvider
extends Object

For this provider to return the actual parameter names, classes must be compiled with the '-parameters' compiler argument. Otherwise, the JDK will return synthetic names in the form arg0, arg1, etc.
