 * <p>
 * The test uses groups of beans with identical collaboration, only differing by the scope one bean
 * per group ({@code SimpleHolderTx} vs. {@code SimpleHolderApp} vs. {@code SimpleHolderDep} ), to
 * verify that transaction scoped beans actually do behave in a different way, compared to
 * application scoped or dependent beans.
