David Capwell commented on CASSANDRA-16147:
-------------------------------------------
I modified split to trigger this logic
{code}
l[i++] = ByteBufferAccessor.instance.sliceWithShortLength(bb, bb.position());
bb.position(bb.position() + 2 + l[i - 1].remaining());
{code}
the test causes the size to be -2 and since the offset is 2 for the header, the
returned buffer is 0
> ValueAccessor is using signed shorts in sliceWithShortLength
