    @greghogan thanks for the review, I have changed the change test to use 
explicit buffer size.
    you are right that currently there is no dependency on this method. We used 
the ByteArrayOutputStreamWithPOs in our own scenario and caught the bug.

> Currently the precondition check in setPosition will fail when the buffer is 
> full: 
> {{Preconditions.checkArgument(position < getEndPosition(), "Position out of 
> bounds.");}}
> We should allow the expected position to be the end position
