Summary

0000672: generating neddoc from INET fails

Description

Both OMNeT++ 4.2.2 and 4.3 stop with the following exception:

An internal error occurred during: "Generating NED Documentation...".
java.lang.IllegalArgumentException: Illegal group reference

It chokes on the @include line in src/inet-doc.ned:

//

// <nohtml>
// @include ../WHATSNEW
// </nohtml>
//

Place of error in the code:

DocumentationGenerator.java:
    private String processIncludes(String comment, Stack<File> parents) throws IOException {
        if (comment.contains("@include")) {
            Matcher matcher = includePattern.matcher(comment);
            StringBuffer buffer = new StringBuffer();

            while (matcher.find()) {
                File dir = parents.peek().getParentFile();
                File file = new File(dir, matcher.group(1)).getCanonicalFile();
                String content = getFileContent(file, parents);
                matcher.appendReplacement(buffer, content); <-----------
            }

            matcher.appendTail(buffer);
            comment = buffer.toString();
        }
        return comment;
    }

The cause might be a JRE regression, because relevant parts of our code haven't changed since 2011.
