TimeZone bug?

Hi all,

In my Application constructor I've got:
    public Application() {
        <...>
        NSTimeZone.setDefault(TimeZone.getDefault());
    }

In a component I have:
    NSTimestampFormatter formatter;
    
    public MyComponent(WOContext context) {
        super(context);
        formatter = new NSTimestampFormatter("%x %I:%M:%S %p");
        formatter.setDefaultFormatTimeZone(new NSTimeZone()); // (1)
    }
    public String currentTimestamp {
        return formatter.format(new NSTimestamp());
    }

(1) if commented out - no exception thrown. If uncommented, I get the exceptions below... any ideas? Is this a bug?

WO 5.2.4, Mac OS X 10.4.1,
java version "1.4.2_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_07-215)
Java HotSpot(TM) Client VM (build 1.4.2-50, mixed mode)

with regards,
