Description

Below function will throws StackOverflowError if no matching line is found for a few consecutive lines.

This will be a common scenario in HA where bundle/coord/WF got executed in other host. For log aggregation we have to search logs in all host and may lead to StackOverflowError.

protected String parseNextLine() throws IOException {
        String line = reader.readLine();
        if (line != null) {
            ArrayList<String> logParts = filter.splitLogMessage(line);
            if (logParts != null) {
                patternMatched = filter.matches(logParts);
            }
            if (!patternMatched) {
                line = parseNextLine();
            }
        }
        return line;
    }
