Description

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".
