as() does not work correctly for any containers based on AbstractDelegatingMutablePicoContainer

    @Test
    public void testAsPropagatesForExactlyOneInvocation() {
        MutablePicoContainer mpc = createPicoContainer(null);
        mpc.change(Characteristics.CACHE);
        
        mpc
        	.as(Characteristics.CACHE).addComponent("bufferTwo", StringBuffer.class, DefaultConstructorParameter.INSTANCE)
        	.as(Characteristics.NO_CACHE).addComponent("bufferOne", StringBuffer.class, DefaultConstructorParameter.INSTANCE)
        	.addComponent("bufferThree", StringBuffer.class, DefaultConstructorParameter.INSTANCE);
        
        assertNotSame(mpc.getComponent("bufferOne"), mpc.getComponent("bufferOne"));
        assertSame(mpc.getComponent("bufferTwo"), mpc.getComponent("bufferTwo"));
        
        //Default behavior is caching.
        assertSame(mpc.getComponent("bufferThree"), mpc.getComponent("bufferThree"));
    	
    }
