prims.cc (_Jv_NewObjectArray): Use _Jv_GetArrayElementFromElementType.
* prims.cc (_Jv_NewObjectArray): Use
_Jv_GetArrayElementFromElementType.
(_Jv_NewPrimArray): Likewise.
* java/lang/natObject.cc (clone): Use
_Jv_GetArrayElementFromElementType instead of sizeof.
* java/lang/natSystem.cc (arraycopy): Use
_Jv_GetArrayElementFromElementType.
* include/jvm.h (_Jv_GetArrayElementFromElementType): New
function.
