Description Antonin Nebuzelsky 2005-01-06 11:10:47 UTC 
Profiler has shown that 49% of the navigator list
populating time has been spent in
java.util.Arrays.sort(). Expanding the sort()
method shows that ClassMemberComparator.compare()
is very expensive because it calls into MDR each time.

duplicate :-) It seems that perf team is really agile :-)
(btw I'm duplicating this one, because Petr's bug includes deeper
explanation of what should be done to improve performance).
