Subject Re: [classlib][icu] there is performance degradation after ICU-related commits
Date Wed, 14 Nov 2007 12:12:31 GMT
Hi all,

I have investigated this problem and found that guilty method is
 SimpleTimeZone/useDaylightTime(), changed by this chunk:

Index: modules/luni/src/main/java/java/util/SimpleTimeZone.java
===================================================================
--- modules/luni/src/main/java/java/util/SimpleTimeZone.java (revision 593468)
+++ modules/luni/src/main/java/java/util/SimpleTimeZone.java (revision 593469)
@@ -837,7 +738,7 @@
  */
  @Override
     public boolean useDaylightTime() {
- return useDaylight;
+ return icuTZ.useDaylightTime();
  }

Please see JIRA for details.

Thanks,
Aleksey,
