I'm using the <service> element in the jar task to generate the appropriate
files to load a service via Java6's java.util.ServiceLoader.

The jar task is incorrectly generating the directory as "service" when it should
be "services", and thus the service loading fails.

I believe the error could easily be fixed in org/apache/tools/ant/taskdefs;

     private void writeServices(ZipOutputStream zOut) throws IOException {
        Iterator serviceIterator;
        Service service;

        serviceIterator = serviceList.iterator();
        while (serviceIterator.hasNext()) {
           service = (Service) serviceIterator.next();
           //stolen from writeManifest
           super.zipFile(service.getAsStream(), zOut,
                         "META-INF/service/" + service.getType(), //should be
"services"
                         System.currentTimeMillis(), null,
                         ZipFileSet.DEFAULT_FILE_MODE);
        }
    }
