Description Alexander Simon 2007-12-14 08:32:31 UTC 
Method consumes about 11% of all parsing time om large projects.
Because method use sequential search in list.
(Example: uts from OpenSolaris contains 5000 elements in list)
Rewrite class to improve performance.
Comment 1 Alexander Simon 2008-01-14 09:22:24 UTC 
fixing: added last search cache. It improves performance in 10 times.
But method still is contained in hot spot (consume 2% of time by JourKit profiler on Open Solaris sources).
Downgrade to P3.

Comment 2 Alexander Simon 2008-01-14 09:25:10 UTC 
Take into account this issue when repository will be refactored.
Comment 3 Vladimir Kvashin 2008-03-24 02:47:37 UTC 
Alexander reduced time spent in this function 10 times.
It isn't now a hot spot.
So I believe the issue is fixed.
