ByteBuffer usage in UDP applications

[arun kumar]

Hello,
    I am using MINA in a UDP application. My IOHandler's messageReceived() 
method has a org.apache.mina.common.ByteBuffer object as the message.
    
    I am modifying the ByteBuffer with the response message and sending using 
the session.write(buf) call.
    
    However this throws an Exception with the message "Already released buffer. 
 You released the buffer too many times."

    If I call buf.aquire() before the session.write() call, I do not get this 
exception.

I added log messages to buf.aquire() and buf.release() methods and found that 
the count was 1 and after calling session.write(buf) the buffer is released 2 
times.Therefore calling aquire() before calling session.write(buf) solved the 
problem.
   
Is this a safe assumption to make for using the ByteBuffer.
Are there other places within MINA code where release() may be called in other 
situations when session.write(buf) is called.

Thanks,
Arun kumar
