	// reflective property accessor is the only one by default
	List<PropertyAccessor> propertyAccessors = ctx.getPropertyAccessors();
	assertEquals(1,propertyAccessors.size());

	StringyPropertyAccessor spa = new StringyPropertyAccessor();
	ctx.addPropertyAccessor(spa);
	assertEquals(2,ctx.getPropertyAccessors().size());
