Thanks! It works.
> subclass of CumulativeDecoder throws an UnsupportedOperationException if

> Key: DIRMINA-548
> URL: https://issues.apache.org/jira/browse/DIRMINA-548
> Project: MINA
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.0-M1
> Reporter: Sangjin Lee
> Assignee: Trustin Lee
> Fix For: 2.0.0-M2
>
>
> If one extends the CumulativeDecoder and finds that there is not enough data
> in the buffer, one returns false on doDecode() so mina can collect more data.
> However, it seems that CumulativeDecoder puts the last remaining bytes from
> the decode into an UnderivableBuffer and stores it in the session. When it
> gets more data later, the data is added to this session buffer, and the
> CumulativeDecoder subclass gets to it.
> Calling methods like slice() and duplicate() on an UnderivableBuffer throw an
> exception. Therefore, your cumulative decoder that does slice() will result
> in an exception.
> See

> for more discussion.
