We've done a lot of G1 testing without seeing this problem, and the likelihood of a GC with G1 right after the thread terminates seem like it would be very rare. I would expect this issue to possibly be somewhat common with a concurrent GC, but not with G1. Maybe there is something about your (automatically configured) default heap size that is causing a GC to be triggered at just the right time.
