Does this extract from the Reference Guide answer your question?
"Gosu types preserve generic type information at run time. This Gosu feature is called reified generics. This means that in complex cases you could check the exact type of an object at run time, including any parameterization. In contrast, Java discards this information completely after compilation, so it is unavailable at run time.
"Note: Even in Gosu, parameterization information is unavailable for all native Java types because Java does not preserve this information beyond compile time. For example the run time type of java.util.List<Address> in Gosu returns the unparameterized type java.util.List."
