<p class="Code">Ideally, the value range for a 3-bit signed integer should be [-4,3]. But the above call to setInt will fail. Essentially, the signed int field in PointerIntPair is behaving the same as an 3-bit unsigned field which has the legal value range
of [0,7]. Is this by design? Are negative values not allowed in PointerIntPair?<o:p></o:p></p>
