JavaRegEx and complex long string

I'm trying to extract the value from the exception by using regular expression in Java. But the string is too complicated and long (all in one line):

I want to extract the Val and SubVal from that string and my pattern is:

^(?:(?:.|\\n|\\r)*)Val=(\\d+);SubVal=(\\d+)(?:(?:.)*)$

I got this exception:

How should I do to extract that Val and SubVal value from that string by using Java RegEx?

I see a lot of extraneous matches; why won't a simple [{]Val=(\\d+);SubVal=(\\d+); work?

Java's RE engine has some problems with repetitions containing alternatives: They get compiled to a recursive function, and on long strings like your's, you get the StackOverflowError.

I'm not sure why you need the ^(?:(?:.|\\n|\\r)*) at the start, and (?:(?:.)*)$ at the end - shouldn't this work without those, too, if you are using find instead of matches?

Here is some example code:

Pattern p = Pattern.compile("Val=(\\d+);SubVal=(\\d+);");

Matcher m = p.matcher(string);
if(m.find()) {
    int val = Integer.parseInt(m.group(1));
    int subVal = Integer.parseInt(m.group(2));
}

(Of course, if you do this several times, make the Pattern some static variable to avoid recompiling it for each use.)
