repeated begin string matches using PatternMatcherInput

["Train, Peter P" <Tr...@scmb.co.za>]

When doing repeated matches against a PatternMatcherInput, if my match
string includes a begin string indicator (^), only the first match works.
It does not look like the CurrentOffset of the PatternMatcherInput is
considered as the beginning of the string to be matched.  A demonstration
can be found in the example below.  Sample output is provided after the
source code.

1) Is this the expected behaviour or should I report it as a bug?
2) Is it possible to change this behaviour so that I can do repeated matches
involving /^.../?


//Source code
import org.apache.oro.text.regex.*;
import org.apache.oro.text.perl.Perl5Util;

class testregex {
    public static void main (String [] args) {
	Perl5Util matcher = new Perl5Util ();
	String testString = "firstsecond";
	PatternMatcherInput matchInput = new PatternMatcherInput
(testString);
	System.out.println ("current offset is " +
matchInput.getCurrentOffset ());
	System.out.println ("remainder of string from current offset is '" +
			testString.substring (matchInput.getCurrentOffset
()) + "'");
	System.out.println ("about to match /^first/");
	if (matcher.match ("/^first/", matchInput))
	    System.out.println ("found match '" + matcher.group (0) + "'");
	else
	    System.out.println ("failed to match /^first/");

	System.out.println ("current offset is " +
matchInput.getCurrentOffset ());
	System.out.println ("remainder of string from current offset is '" +
			testString.substring (matchInput.getCurrentOffset
()) + "'");
	System.out.println ("about to match /^second/");
	if (matcher.match ("/^second/", matchInput))
	    System.out.println ("found match '" + matcher.group (0) + "'");
	else
	    System.out.println ("failed to match /^second/");
    }
}


sample output:
current offset is 0
remainder of string from current offset is 'firstsecond'
about to match /^first/
found match 'first'
current offset is 5
remainder of string from current offset is 'second'
about to match /^second/
failed to match /^second/
