------------------------------------
Hi [~Sammi],
Thanks for working on this.
1. Looks like we need to add changes for Windows platform.
2. Could we follow the pattern for the tests for RS raw coder to do the tests
here? It can share the test cases between Java impl and native impl for the
same codec.
Thanks.

> Raw XOR coder is utilized in Reed-Solomon erasure coder in an optimization to
> recover only one erased block which is in most often case. It can also be
> used in HitchHiker coder. Therefore a native implementation of it would be
> deserved for performance gain.
