See also VerifyTest1.j. ; ; The main() method below tries to clone the integer 100 - this ; is clearly an error since clone() expects an Object, not an integer. ; ; If you run this with no verification on, it is likely to crash the ; interpreter. Running this with the -verify option produces a ; Verifier error. ; ; This is similar to the Java code: ; ; class VerifyTest { ; public static void main(String args[]) { ; int x = 100; ; x.clone(); ; } ; } .class public examples/VerifyTest .super java/lang/Object .method public ()V aload_0 invokenonvirtual java/lang/Object/()V return .end method .method public static main([Ljava/lang/String;)V bipush 100 invokevirtual java/lang/Object/clone()Ljava/lang/Object; return .end method
