	I believe I have identified the actual cause of the issue. &nbsp;As I thought the join logic is entirely correct however the logic used when finding distinct solutions for a TriplePattern based on previous bindings turns out to be flawed.</p>
<p>
	&nbsp;</p>
<p>
	The fix should simply be to correct the logic in SetDistinctnessComparer</p></td>
