Is it possible to get rid of Polchinski's paradox with kindergarten STR maths?
This online quote from Kip Thorne's excellent semi-popular book "Black Holes & Timewarps" says yes. [add]But the analysis may not be relativistic.
A more detailed paper would be http://prola.aps.org/abstract/PRD/v44/i4/p1077_1 (but I haven't read it personally, it's on my to-read list).
Reading this paper seems to suggest that the billiard balls analyzed were not relativistic, though. I don't know for sure if anyone has done the relativistic case.
Your help is very much appreciated. Thank you.
