Much more. Many of the library classes call native methods to do the heavy lifting; every one of those methods has to be implemented and debugged anew for each platform. (For example, the "concurrency" classes require the implementation of the machinery which allows lock-free access to variables shared across threads.)

I disagree with this assertion, if it is meant to imply that Apple coudnt write a 1.5 version for older mac OSs, at least 10... the low-level OS abstraction layers can almost ALWAYS be implemented even on old platforms, or at least emulated (except for some overly complex native window stuff). If one doesnt "believe" this statement, witness how Suns newest JVMs operate even on the other OS's that are 8 years old (albeit with handicapped Swing). Sun provides the missing, "machinery" as native or bytecode if the native OS doesnt provide it.

I truly regard Apples lack of commitment to providing newer JVM availability, for their older OSs, as a greedy sales motivator (not just in java APIs either, sorry to say)and/or being due to lack of programmer resources. Making the 1.5(5) jvm only available for Panther is just bad for the community, becasue it produces as many compatibility problems as, say, using native code would. Sad.
