> The problem appears in Log4j 2.0-beta6 and in revision 1490297. I
> attached a one-line patch that fixes it.
> In the static initialization block for "UUIDUtil", the loop over
> "sequences" should break immediately after "duplicate" is set to
> "true". All the iterations after "duplicate" is set to "true" do not
> perform any useful work, at best they just set "duplicate" again to
> "true".
