32-bit client java HotSpot VM (build 1.4.0-beta-b56) fails to pass the test

    nsk/regression/b4257171
    
on Solaris Sparc in -Xcomp mode.

The test passes on all other platforms and modes.
    
Due to the specification for the method
java.lang.System.arraycopy(java.lang.Object, int, java.lang.Object, int, int)

    "...
     an IndexOutOfBoundsException is thrown and the destination is not modified:
       - The srcOffset argument is negative.
       - The dstOffset argument is negative.
       - The length argument is negative.
       - srcOffset+length is greater than src.length,
         the length of the source array.
       - dstOffset+length is greater than dst.length,
         the length of the destination array."
         
    "...
     Throws:
     ArrayIndexOutOfBoundsException - if copying would cause access of
                                      data outside array bounds.
     ArrayStoreException - if an element in the src array could not be
                           stored into the dest array because of a type
                           mismatch.
     NullPointerException - if either src or dst is null."
     
The spec does not clarify what exception will be thrown if
srcOffset equals to Integer.MAX_VALUE and length > 0.

Anyway, the following test expects ArrayIndexOutOfBoundsException,
but neither IndexOutOfBoundsException, nor ArrayIndexOutOfBoundsException
is thrown.

import java.io.PrintStream;

public class b4257171 {

    public static void main(String argv[]) {
System.exit(run(argv, System.out) + 95/*STATUS_TEMP*/);
    }

    public static int run(String argv[], PrintStream out) {
int a1[] = {1, 2, 3};
int a2[] = {4, 5, 6};
try {
System.arraycopy(a1, Integer.MAX_VALUE, a2, 0, 3);
} catch (ArrayIndexOutOfBoundsException e) {
return 0/*STATUS_PASSED*/;
}
return 2/*STATUS_FAILED*/;
    }

}

The failure looks like a regression of the known bug

The test belongs to the testbase_nsk testbase located at:
