The SimpleDateFormat.<init> was faster on 1.3.1 than on 1.4, see the attachment.

EVALUATION
With the following test program,
import java.text.SimpleDateFormat;
public class NewSimpleDateFormat {
public static void main (String args[]) {
for (int i = 0; i < 10000; i++) {
new SimpleDateFormat("yyyy.MM.dd G 'at' HH:mm:ss z");
}
}
}
Total (usr+sys) CPU times in 1.4 (b76) and 1.3.1 are:
1.4 b76: 1.75 sec [1.64 + 0.11]
1.3.1: 1.77 sec [1.61 + 0.16]
The platform is Solaris 8/Ultra-60 (450MHz). tcsh is used to measure CPU time.
The usr CPU time in 1.4 b76 is slightly larger (~2%) because of the 4326988 fix. But 1.4 b76 is still faster than 1.3.1 (in total CPU time).
