The msg.setAutoExpand(true) causes the buffer to automatically change
the capacity and limit. If you need the exact size, you have to take
care of it yourself (i.e. determine the buffer size beforehand, allocate
it and setAutoExpand(false) ).

Hello. I'm using MINA 1.1.2
I have a question about ByteBuffer.allocate();
Let me show you code.
--
ByteBuffer msg = ByteBuffer.allocate( 9, false );
msg.setAutoExpand( true );
msg.put( (byte)0x01 ); // 1 byte
msg.putShort( (short)0x01 ); // 2 byte
msg.put( (byte)0x01 ); // 1 byte
msg.put( (byte)0x01 ); // 1 byte
msg.putInt( 0 ); // 4 byte
msg.put( (byte)0x01 ); // 1 byte
msg.put( (byte)0x01 ); // 1 byte
msg.put( (byte)0x01 ); // 1 byte
msg.put( (byte)0x01 ); // 1 byte
logger.debug( msg.limit() ); // output is 16
but, ByteBuffer msg = ByteBuffer.allocate( 8, false );
logger.debug( msg.limit() ); // output is 13
what's the reason?
