>
> Mapper release 1.1.13 created a regression in the treatment of Adapter
> implementations that indirectly inherit from Adapter.
> "Indirect inheritance" is such that the type does not directly implement
> Adapter, but extends some other type that implements Adapter).
> A brief look into the cause of the issue is that the "reverse" adapter key
> cannot be found/determined and causes a NullPointerException to be thrown
> when trying to utilize the null AdapterKey.
> It should be noted that this behavior worked without issue in 1.1.12.
> Attached is a test case that exemplifies the issue.
