Jdeveloper 10g ojvm changing defaultCenturyStart

Question

I have an application that runs fine using the java 1.4.1_05 jvm (hotspot or server) but when I run it using the 10g ojvm, after I execute the first prepartes statement, all my java.util.date objects go really strange.
Here is the code I am using to trace the problem.
protected static SimpleDateFormat s_dateFormat = new SimpleDateFormat("MM-dd-yyyy HH:mm:ss.SSS ");
Date newDate = Calendar.getInstance().getTime();
String preDateTime = s_dateFormat.toPattern() + " | " +
s_dateFormat.get2DigitYearStart() + " | " +
s_dateFormat.format(newDate) + " " + newDate.toString() +
" " + s_dateFormat.toLocalizedPattern();
The output looks like
MM-dd-yyyy HH:mm:ss.SSS | Mon Dec 03 16:35:23 EST 1923 | 12-03-2003 16:35:31.531 Wed Dec 03 16:35:31 EST 2003 MM-dd-yyyy HH:mm:ss.SSS
but then when I execute my first prepared statement, the same method starts outputing
MM-dd-yyyy HH:mm:ss.SSS | Wed Dec 02 21:16:41 EST 230747998 | 11-05-232044683 05:59:13.030 Mon Nov 05 05:59:13 EST 232044683 MM-dd-yyyy HH:mm:ss.SSS
MM-dd-yyyy HH:mm:ss.SSS | Wed Dec 02 21:16:41 EST 230747998 | 08-18-232078099 16:34:27.231 Tue Aug 18 16:34:27 EDT 232078099 MM-dd-yyyy HH:mm:ss.SSS
MM-dd-yyyy HH:mm:ss.SSS | Wed Dec 02 21:16:41 EST 230747998 | 05-10-232078243 17:38:51.807 Wed May 10 17:38:51 EDT 232078243 MM-dd-yyyy HH:mm:ss.SSS
so the s_dateFormat.get2DigitYearStart() is now 230747998?
If I tell 10g to use any other jvm, the times are ok.
Does the ojvm try to syncronize the database time and the system time or something weird like that?
Looks like a bug to me, wasn't sure where to post that.

Answer 1

Actually let me refine my answer. With the examples I tried it doesn't reproduce. If you could post a complete example that fails for you, I can give that a try as well.
Thanks again,
