	// reflective method accessor is the only one by default
	List<MethodResolver> methodResolvers = ctx.getMethodResolvers();
	assertEquals(1, methodResolvers.size());

	MethodResolver dummy = new DummyMethodResolver();
	ctx.addMethodResolver(dummy);
	assertEquals(2, ctx.getMethodResolvers().size());

	List<MethodResolver> copy = new ArrayList<>();
	copy.addAll(ctx.getMethodResolvers());
	assertTrue(ctx.removeMethodResolver(dummy));
	assertFalse(ctx.removeMethodResolver(dummy));
