Is there a well-known implementation, that has friendly open-source licensing (not GPL), of an ECC (error correcting code) library (e.g. Reed-Solomon) for Java?
Apache License (not sure if that counts in your definition of friendly) I am also not sure if it counts as well known (google knew about it, no 2 result for "java Reed-Solomon")?
I have implemented Java wrappers for the JErasure Library written by Plank et al. in C.
If you do not mind the native dependency, then JErasure is an excellent choice (if not the best). Until someone ports JErasure to Java, you will have to concise on performance as the implementation in zxing is not that fast when working on larger blocks of data.
I have put the code on GitHub: https://github.com/jvandertil/Jerasure
