Classes.zip has DateFormatZoneData_iw.class and
LocaleElements_iw.class files, but not DateFormatZoneData_he.class and
LocaleElements_he.class files. "iw" is the old ISO-639 language
abbreviation for Hebrew and "he" is the new one. Windows NT uses the
new ISO abbreviation as opposed to the old. With JDK 1.1.5, if the
Hebrew locale is selected as the default locale via Control Panel
Regional Settings, Java returns "he" instead of "iw".
 
So, in 1.1.5, the resource files DateFormatZoneData_iw.class and
LocaleElements_iw.class were misnamed. If you ran JDK 1.1.5 FCS or
1.1.6B, and asked for locale info, you would get an answer of "he",
even though the resource files had the "iw" suffix.
 
Now, from JDK 1.1.6B and onwards, when you set the Regional Setting in
WinNT to Hebrew, the default locale now comes back as "iw" (1.1.6E) as
opposed to "he" (1.1.6B, 1.1.5FCS, etc.).
 
Since the new ISO code for Hebrew is "he", Java should use "he" as the
locale abbreviation and as a resource filename suffix.
