Java library for error-correction

Question

I am looking for a simple error-correction library in Java.

It needs to be able to correct some errors in variable-length messages. However, the error-correcting codes together with the message must have a fixed-length (for transmission).

Mathematical complexity or time to decode isn't a concern.

Edit: I am transmitting data over sound. The errors that usually occur are single bit-errors but sometimes also larger bursts. Shifting of the entire message and Erasure of bits are not an issue.

This one is excellent. Fast and extremely flexible in that you can use pretty much any combination of data/parity blocks you want.
