Summary: Crash of due to a NumberFormatException in
XMPSchemaAdapter (problem of GMT parsing)
Product: XMLGraphicsCommons
Version: 1.4
Platform: PC
OS/Version: Linux
Status: NEW
Severity: blocker
Priority: P2
Component: XMP

Hi there !
I think there is an issue in the method formatISO8601Date of the class
org.apache.xmlgraphics.xmp.XMPSchemaAdapter
When you have a negative GMT indication and when the negative number is less or
equal to -10 then there is a problem.
The piece of code:
if (zoneOffsetHours > 0) {
sb.append('+');
} else {
sb.append('-');
}
if (zoneOffsetHours < 10) {
sb.append('0');
}
If I have zoneOffsetHours = -10 I will have zoneOffsetHours < 10 true (-10 <
10) so I will have sb concatenated with “-010” and not with “-10”.
The result is : 2011-04-07T08:12:11-010:00
I think we should have 2011-04-07T08:12:11-10:00 (no zero before the -10).
It causes a NumberFormatException in my case, if I use FOP. the error is in the
parseISO8601Date method of the same class :
The line that crashes is the following :
offset += Integer.parseInt(timeZonePart.substring(4, 6));
The result of timeZonePart.substring(4, 6) is :0 and not 00 as it should be.

As a result, each part of the word that has a GMT -10,-11,-12,-13 (Tonga)
cannot use FOP 1.0. It is the case for many Pacific islands (I'm in French
Polynesia).
I think that the good test would be :
if (Math.abs(zoneOffsetHours) < 10) {
sb.append('0');
}
