[jboss-user] [Javassist user questions] - Re: interface weirdness

I have had the same problem. I have a class which contains this code: List x = new ArrayList(); | x.add(new ArrayList()); and I instrument it with an editor which replaces the call to method add with: "$_ = ($r)$proceed($1 instanceof java.lang.Object ? $1 : $1);" When I run the program, the loading of the class generates the error: Exception in thread "main" java.lang.VerifyError: (class: Test, method: main signature: ([Ljava/lang/String;)V) Inconsistent args_size for opc_invokeinterface If the type of variable x is "AbstractList" instead of "List", the program runs normally. I did some experiments and I think the "cond ? ex1 : ex2" expression is the cause of the problem... but why?
