AutoCloseable when not available

On his blog, Brian Oxley shows a neat way in JDK 8 to use non AutoCloseable object having a close-like method in a try with resources construct, using the new method references. For those of us who are still stuck with JDK 7 for some time, here is the (uglier) equivalent code:

	final Foo foo = new Foo();
	try (AutoCloseable ignore = new AutoCloseable() {
		@Override
		public void close() {
			foo.close();
		} 
	}) {
		foo.doFoo();
	}
