* Default implementation of the {@link ParameterNameDiscoverer} strategy interface,

* {@link LocalVariableTableParameterNameDiscoverer} for checking debug information
* in the class file.
*
* <p>If a Kotlin reflection implementation is present,
* {@link KotlinReflectionParameterNameDiscoverer} is added first in the list and
* used for Kotlin classes and interfaces.
*
* <p>Further discoverers may be added through {@link #addDiscoverer(ParameterNameDiscoverer)}.
