             Summary: LicenseAddingReport#report has useless call to metaData.getData
                 Key: RAT-148
                 URL: https://issues.apache.org/jira/browse/RAT-148
             Project: Apache Rat
          Issue Type: Bug
          Components: reports
            Reporter: Chris A. Mattmann
             Fix For: 0.9


While perusing the current trunk code, I noticed that LicenseAddingReport.java#report has a useless call to metaData.getData:

{code:java}

public class LicenseAddingReport extends AbstractReport {
    private final AbstractLicenceAppender appender;

    public LicenseAddingReport(String pCopyrightMsg, boolean pForced) {
        appender = pCopyrightMsg == null ? new ApacheV2LicenceAppender() : new ApacheV2LicenceAppender(pCopyrightMsg);
        appender.setForce(pForced);
    }

    @Override
    public void report(org.apache.rat.api.Document document) throws RatException {
        final MetaData metaData = document.getMetaData();
        final Datum licenseHeader = metaData.get(MetaData.RAT_URL_HEADER_CATEGORY);
        if (licenseHeader == null
                ||  MetaData.RAT_LICENSE_FAMILY_CATEGORY_DATUM_UNKNOWN.getValue().equals(licenseHeader.getValue())) {
            final File file = new File(document.getName());
            if (file.isFile()) {
                try {
                    appender.append(file);
                } catch (IOException e) {
                    throw new RatException(e.getMessage(), e);
                }
            }
        }
        metaData.getData();
    }
}
{code}

Looks to me that metaData is a local final variable, and that the call to getData returns a MetaData object, which in turn is never used.
