> ReflectiveRelMetadataProvider's constructor verifies that it is not created
> with an empty map, using an assertion. However, this is not the most reliable
> way of verifying this situation, since assertions can be deactivated. In such
> scenario, we could silently end up having an invalid
> ReflectiveRelMetadataProvider, with no actual methods attached.
> Also, since the map is private and has no getter, there is no way for a
> caller module to verify this situation on its side.
> For this reason, it is proposed a minor change: replace the assertion with an
> IllegalArgumentException, which will work in 100% of the cases and will
> always prevent constructing an invalid ReflectiveRelMetadataProvider.
