Review comment:
@sijie the first time getEntry is called we will set data to null, this way
the client cannot re-use the buffer anymore.
On an eventual "second call" we will throw an IllegalStateException which
explains the error.
if I drop the 'if' the user will get a NullPointerException, but this is not
very clear and IMHO it is bad practice.
Unfortunately the ByteBuf can be used only once, because we have no clue to
reset the original start position for the entry
