Keith Turner commented on ACCUMULO-4113:
----------------------------------------
Another type of bug I have discovered is code calling
{{ByteBuffer.get(byte[])}}. The {{get()}} method advances the byte buffers
position, which is not the intention of the code calling {{get()}}.
> Fix incorrect usage of ByteBuffer

> While working on ACCUMULO-4098 I found one place where ByteBuffer was being
> used incorrectly. Looking around the code, I have found other places that
> are using ByteBuffer incorrectly. Some of the problems I found are as
> follows :
> * Calling {{ByteBuffer.array()}} without calling {{ByteBuffer.hasArray()}}.
> * Using {{ByteBuffer.position()}} or {{ByteBuffer.limit()}} without adding
> {{ByteBuffer.arrayOffset()}} when dealing with an array returned by
> {{ByteBuffer.array()}}.
> * Using {{ByteBuffer.arrayOffset()}} without adding
> {{ByteBuffer.position()}} when dealing with an array returned by
> {{ByteBuffer.array()}}.
