Java HotSpot Server and Client VMs (build 1.4.0-beta-b59, build 1.3.1-rc1-b21)
fail to pass the test

    nsk/jdi/ArrayReference/getValues/getvalues002
    
This failure was observed on all platforms and in all modes.
    
The test checks if ArrayReference.getValues() method returns all
of the components in this array.

Debuggee (getvalues002a file) declares 13 fields with empty arrays of
values of primitive types:

    static boolean z1[] = {};
    static byte b1[] = {};
    static char c1[] = {};
    static double d1[] = {};
    static float f1[] = {};
    static int i1[] = {};
    static long l1[] = {};
    static short r1[] = {};

    static final long lF1[] = {};
    static private long lP1[] = {};
    static public long lU1[] = {};
    static protected long lR1[] = {};
    static transient long lT1[] = {};
    static volatile long lV1[] = {};
    
Debugger (getvalues002 file) finds each field by name, gets its value and
casts the value to ArrayReference type. Then debugger tries to invoke the
method getValues(), but IndexOutOfBoundsException is always thrown.

The specification of method ArrayReference.getValues() says nothing about
throwing IndexOutOfBoundsException even if array in debuggee is empty:

    public List getValues()
    Returns all of the components in this array.
    Returns: a list of Value objects, one for each array component ordered by
             array index.
    Throws: ObjectCollectedException - if this object has been garbage
            collected.
            
Since the method getValues() returns List with N (N > 0) elements for array that consists
of N components in debuggee, I guess getValues() should return empty list for empty
array instead of throwing IndexOutOfBoundsException
