> Any newly created dynamic buffer has 0 capacity, and a new space is allocated on demand (i.e. lazily).  However, this causes a lot of confusion to users.  For example:  The following code fails with IndexOutOfBoundsException:
>     ChannelBuffer buf = ChannelBufers.dynamicBuffer(1500);
>     buf.setIndex(0, 1000);
> where it should not fail because user asked for at least 1600 bytes.  There's not much gain from the lazy initialization - it just gives user confusion, hence the internal buffer should be initialized immediately.
