Semantically there aren't equivalent but it should not be a problem if you don't use asType to do an unboxing conversions e.g. Integer or Object -> int if the object is null asType throws a NPE but explicitCastArguments returns 0. > > -- John Rémi _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
