Hi Peter,

I also don't know whether having LinkedHashMap instead of plain HashMap is necessary, since it is initialized with defaults from plain HashMap (which is hashCode % capacity ordered) and only some of defaults are overridden in parsing loop in general. For example, having this annotation:

@interface Ann { String one(); String two() default "2"; } and usage: @Ann(one = "1") ...toString will print: @Ann(two = "2", one = "1")

While there perhaps is no natural ordering between the sets of default elements and non-default elements you probably want an order following source as closely as possible among the non-default elements.
