We would like to keep the documentation and specification as readable as possible while still being sufficiently exacting so that behaviour of an API can be correctly predicted by a reader. It goes further than that though because Oracle employs an entire group of engineers who examine the JDK API javadocs looking for normative statements and then write tests to confirm that implementations conform to the API documentation/specification.  The number and quality of tests they provide to ensure conformance has been steadily increasing (and accelerating). Is this a good thing? To me it seems so. When I hear that people encounter problems (other than performance) when switching among Vector<->ArrayList<->LinkedList<->CopyOnWriteArrayList or HashMap<->ConcurrentHashMap or TreeSet<->ConcurrentSkipListSet because of arbitrary corner case differences between implementations I become smy

Sorry, replying to my own message to finish an incomplete sentence.

...sympathetic to concerns that the JDK docs/specs are not specific enough.
