Review Comment:
The error message for duplicate keys should include the key itself. Update
the message to: throw new RuntimeException(String.format("Duplicate key %s for
values %s and %s", key, v1, v2));
```suggestion
throw new
RuntimeException(String.format("Duplicate key %s for values %s and %s", v1,
v2));
```
