subclass of CumulativeDecoder throws an UnsupportedOperationException if
IoBuffer.slice() is used
-------------------------------------------------------------------------------------------------
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
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.
