JDK-4452610 - HS1.4: Server VM crashes with the error at vframeArray.cpp,89
Description
michael.parks@eng 2000-04-17

verified on Intel only.

If attempting to access an element of 
an uninitialized array using a negative index,
the VM throws an ArrayIndexOutOfBoundException 
instead of a NullPointerException.

The error occurs with java switch "-Xcomp" turned on,
and does not arise if "-Xcomp" is omitted.
