Unable to map class with self-referencing generics and Comparable return type

The attached testcase fails constructing the mapping factory when mapping a 
class. The class has self referential generics (Foo <T extends Foo<T>>) and 
also a getter that returns an Optional<Range<String>>. The mapping construction 
will fail with the following exception:

Caused by: java.lang.IllegalArgumentException: types Foo and Range<String> are 
not comparable

    at ma.glasnost.orika.property.IntrospectorPropertyResolver.collectProperties(IntrospectorPropertyResolver.java:83)

The Optional<Range<C extends Comparable<C>>> does work without the self 
referential generics, and the self referential generics work as advertised when 
used without the getter returning the Optional<Range<C...>

See the attached test case for the failure.
