There appears to be a performance regression problem with the 6271375, 6274985, and 6276059 fixes. DateFormat test test/java/text/Format/DateFormat/Bug4322313.java takes 41 seconds on SunFire v65z. It should take only 0.5 seconds.

DateFormatSymbols.getZoneStrings() is very expensive because it has to duplicate a String[][].

relates to

JDK-6274985 TimeZone.getDisplayName() should not rely on DateFormatSymbols.getZoneStrings()

Resolved

JDK-6276059 Inconsistent handling of localized names from TimeZoneNameProvider

Resolved

JDK-6594712 [Fmt-Da] subclasses of DateFormatSymbols can have MASSIVE performance issues

Closed

JDK-6271375 DateFormatSymbols should initialize zoneStrings array when needed
