java.util.Arrays

Subject: java.util.Arrays

For the java.util.Arrays class, I've attached three new tests and
patches for the two existing tests (both patches add further checks). 
With JamVM 1.1.4 I get a number of failures.  The first two I think are
due to a bug in JamVM (see my post earlier today re: Float.compare() and
Double.compare()).  I haven't investigated the other failures in detail,
but they are all very similar and probably have the same underlying
cause (I may have some time next week to look at this more closely). 
All checks pass using Sun's JDK 1.4:
