Naveen Neelakantam updated HARMONY-3222:
----------------------------------------

    Attachment: imm_cast_bug.patch

This patch (imm_cast_bug) fixes the issue.  The problem is with casting.  Basically the following was occuring:

in32 cast to uint32 cast to int64

As a result, negative constants would become large positive constants:

-1 cast to 4294967295 cast to 4294967295

If this casted value was used to dereference an array it would be multipled by the array element size (let's say 4),  which would exceed the maximum value that could fit in a 32-bit integer:

4294967295* 4 = 17179869180
