[Martin Buchholz]

Thanks for reusing the existing testing infrastructure I wrote many years
ago.

I'm a big fan of diversity in testing, and so I much prefer using a
different random seed every time to the "reliability" of deterministic
tests.  I you wanted to add repeatability support, you could easily have
the test save the initial seed and provide it in case of failure.


-    static final Random rnd = new Random();+    static final Random
rnd = new Random(8675309);

I don't like the removal of tests below.  Can we find some other way of
handling this (perhaps by catching NotSerializableException, as I did in
MOAT.java?)
                    if (! (xxx.getCause() instanceof
NotSerializableException))

-        if (maybe(4) && s instanceof Serializable)-
equal2(s, serialClone(s));+// mduigou: I had to comment this out for
the Collection wrappers which wrap+// unserializable sets.+//
if (maybe(4) && s instanceof Serializable)+//            equal2(s,
serialClone(s));
