KernelJRE picks wrong TimeZone.
For the TimeZone: America/Los_Angeles and Locale :en_US
KernalJRE picks the ZONE as GMT but it should be PST.

<tescase>
import java.util.*;

public class Foo {
private static String[] calendar_formats = {
"%ts' (0 - 99...?)",
"%tz (-1200 - +1200) ZONE_NUMERIC",
"%tZ ZONE (symbol)",
" DATE_TIME %tc (Sat Nov 04 12:02:33 EST 1999)",
        };
public static void main(String... arg) {
TimeZone tz = TimeZone.getTimeZone("America/Los_Angeles");
Locale local = new Locale("en_US");
Calendar c = new GregorianCalendar(tz, local);
c.clear();
c.set(1977, 10, 15);
StringBuffer sb = new StringBuffer(58);
Formatter formatter = new Formatter(sb);
for(String format: calendar_formats) {
formatter.format(format+" \n",c);
}
System.out.println(sb.toString());
}
}
</testcase>
