> |0x043C|1084|_(Photoshop CS5)_ Macintosh NSPrintInfo. Variable OS specific info for Macintosh. NSPrintInfo. It is recommened that you do not interpret or use this data.|
>  
> Here is some simple test code that replicates what our application is trying to do, and recreates the error:
> {code:java}
> import java.util.regex.Matcher;
> import java.util.regex.Pattern;
> public class RegexMatches {
>     public static void main(String args[]) {        // String to be scanned to find the pattern.
>         String line = "This order was placed for QT3000! OK?";
>         String pattern = "(.*)(\\d+)(.*)";        // Create a Pattern object
>         Pattern r = Pattern.compile(pattern);        // Now create matcher object.
>         Matcher m = r.matcher(line);
>         if (m.find()) {
>             System.out.println("Found value: " + m.group(0));
>             System.out.println("Found value: " + m.group(1));
>             System.out.println("Found value: " + m.group(2));
>         } else {
>             System.out.println("NO MATCH");
>         }
>     }
> }{code}

> Here is the resulting error:
