/**
 * 
 * Used for injecting non-fail-fast zookeeper client classes.
 * 
 * Here is why:
 * 
 * <ul>
 * <li>tests contained in a single junit class are not forked: forking is on a class basis</li>
 * <li>zookeeper client classes are injected during the tests</li>
 * <li>zookeeper server is restarted between test methods.</li>
 * <li>zookeeper client classes from previous tests methods get a "expired" exception upon reconnection to the new
 * zookeeper instance. With a fail-fast implementation, this would kill the current test.</li>
 * </ul>
