RE: Problems setting up ozone on w2k

[Falko Braeutigam <falko@softwarebuero.de>]

David and all,

to avoid the IllegalArgumentException problem, which is probably caused by the
jdk which doesn't return the method array of a class in the same order each
time the getMethods() method of Class in invoked, I have included some code to
sort the array before OPP generates the proxy code and before the core uses the
method array to find the proper method from the method array index, which the
proxy has sent.

Right now I'm re-working the Lock code which still causes some trouble. As soon
as I get this working I will release a new package, so that you can check things
on w2k.
