 * A <a href="http://jackrabbit.apache.org/filevault">Jackrabbit FileVault</a> install hook

 * <p>The new {@link org.apache.jackrabbit.vault.packaging.InstallHook} interface is only supported since bundle {@code com.day.jcr.vault} 
 * in version 2.5.10 (AEM 6.0 SP3 and AEM 6.1).
 * Previous versions of that bundle (and more specifically the {@code com.day.jcr.vault.packaging.impl.JrVltInstallHookProcessor$Hook#loadMainClass(...)} 
 * only support the old interface at {@code com.day.jcr.vault.packaging.InstallHook}</p>
