Distribution Sun Java Desktop R2
Also tested under solaris, same results

A DESCRIPTION OF THE PROBLEM :
We are facing some parsing problems in j2se 1.3.1_11, j2se 1.3.1_12 that working in previous releases <= j2se 1.3.1_10 and in the new J2SE 1.4.2_05

Parsing dates string with lenient off gives wrong results ( i think the dayligth savings are added to date)


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Just run the test case with jdk1.3.1_11 (or jdk1.3.1_12) to obtain a wrong output and with
and <= jdk1.3.1_10 or 1.4.2_05 to obtain the expected result

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I allways expected that parsing the same string with the same date format, give the same date in different versions of J2SE
ACTUAL -
Using jdk1.3.1_11 (Result NOT OK)
Lenient is 1 parse 2004-08-10 20:12:15 DateTime=1092165135000 DateToString=Tue Aug 10 20:12:15 BST 2004
Lenient is 0 parse 2004-08-10 20:12:15 DateTime=1092168735000 DateToString=Tue Aug 10 21:12:15 BST 2004

Note that in the output "Lenient is 0 parse..." the sames date format was used to parse the same date, but with lenient off, and 1 hour was added to the date, with the same timezone (Europe/London)


Using jdk1.3.1_10 (Result OK)
Lenient is 1 parse 2004-08-10 20:12:15 DateTime=1092165135000 DateToString=Tue Aug 10 20:12:15 BST 2004
Lenient is 0 parse 2004-08-10 20:12:15 DateTime=1092165135000 DateToString=Tue Aug 10 20:12:15 BST 2004

Using jdk1.4.2_05 (Result OK)
Lenient is 1 parse 2004-08-10 20:12:15 DateTime=1092165135000 DateToString=Tue Aug 10 20:12:15 BST 2004
Lenient is 0 parse 2004-08-10 20:12:15 DateTime=1092165135000 DateToString=Tue Aug 10 20:12:15 BST 2004


REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
public class LenientTest {

public LenientTest() throws Exception {

TimeZone.setDefault(TimeZone.getTimeZone("Europe/London"));

final DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date dt;

df.setLenient(true);
String time = "2004-08-10 20:12:15";
dt = df.parse(time);
outputDate(1, time, dt);
df.setLenient(false);
dt = df.parse(time);
outputDate(0, time, dt);
}

private static final void outputDate(int lenient, String time, Date dt) {
System.out.println("Lenient is " + lenient + " parse " + time + " DateTime=" + dt.getTime() + " DateToString=" + dt);
}

public static void main(String[] args) throws Exception {
LenientTest untitled11 = new LenientTest();

}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Use <= j2se 1.3.1_10, or j2se 1.4 (tested only with j2se_1.4.2_05)
