{@code ByteBuffer}s are stateful. Calling their {@code get} methods changes their {@code position}. We recommend
using {@link java.nio.ByteBuffer#asReadOnlyBuffer()} to create a read-only view of the buffer with an independent
{@code position}, and calling {@code get} methods on this rather than directly on the returned {@code ByteBuffer}.
Doing so will ensure that anyone else using the {@code ByteBuffer} will not be affected by changes to the
{@code position}.
