This was a purely code refactoring task, which among other things refactored some anonymous inner classes in `TypeConverterFactory.java` and `ClassMap.java` to lambdas. All the lines that failed to apply cleanly were deletes, so after this change these differences no longer even exist.

There should be a better reviewer but time is nigh: ship it!
