You need to re-initialise the cipher object before decryption. Acorn128 keeps track of the current stream position. The encryption request is for bytes 0 to 15 and the decryption request is for bytes 16 to 31. Because the offsets are different they will encrypt/decrypt differently.
You should call setKey(), setIV(), and optionally addAuthData() again before decryption to reset the stream offset to 0. See the TestAcorn example code for the pattern.

Oh, thanks a lot!
I was thinking that IV is optional.
I was experimenting with this library, and I found that length of IV must be exact 16. Otherwise decryption fails.
