beginOffset() returns invalid values

           Summary: beginOffset() returns invalid values
           Product: ORO
           Version: 2.0.6
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: Main
        AssignedTo: [email protected]
        ReportedBy: [email protected]


The following code:

   AwkStreamInput input = new AwkStreamInput(new FileReader(genomeFile));
   org.apache.oro.text.regex.Pattern p = new AwkCompiler().compile
(anchorPatternStr);
   AwkMatcher matcher = new AwkMatcher();

   while( matcher.contains(input, p))
        System.err.println("found at " + matcher.getMatch().beginOffset(0));

Produces this output:

found at 110
found at 460
found at 931
found at 1027
found at 413
found at 1657
found at 1756
found at 1946
found at 0
found at 55
found at 529
found at 816
found at 1965

offset values are clearly wrong, as they are supposed to be increasing.
