    @Override
public void onMessage(final Message message) {
    try {
        LOG.fine("waiting on semaphore for " + message);
        semaphore.acquire();
        LOG.fine("semaphore acquired for " + message);
        listener.onMessage(message);
        LOG.fine(message + " processed");
    } catch (final InterruptedException e) {
        throw new RuntimeException(e);
    } finally {
        semaphore.release();
    }
}
