The code is as follows Class c = Customers.class; // called in main & Customer class just has a double[] Dubs = new double[10] CreateType(c); // Main     public static Object CreateType(Class genericType) {         // some preReq declarations         CtMethod writeCode = dyn.getDeclaredMethod("processCode");           generateCode(genericType, Code, "temp"); // Code is a StringBuilder class           System.out.println(Code);           writeCode.insertAt(1, Code.toString()); // Compilation is successful           Class c = dyn.toClass();           Dynamic h;         Constructor[] ctorlist = null;           ctorlist =  c.getDeclaredConstructors(); // Problem is here           h = (DynamicSurrogate) ctorlist[0].newInstance(genericType);           return h; }     Generated code is as follows testapp1.Customers temp=(testapp1.Customers)graph;     output.processDouble(temp.Dubs[1]); But problem arises when getDeclaredConstructors is called c.getDeclaredConstructors() ... it throws the following error Exception in thread "main" java.lang.VerifyError: (class: testapp1/Dyn, method: processDouble signature: (Lsomething/Output;Ljava/lang/Object;)V) Inconsistent args_size for opc_invokeinterface A workaround exists but does not make any sense, i.e. everything works fine if i simply create a copy of the double array and pass it on to processDouble in dynamic codei.e. if the dynamic code is testapp1.Customers temp=(testapp1.Customers)graph;     double[] d = temp.Dubs;     output.processDouble(d); n short , exception Unhandled is thrown by getDeclaredConstructor but it actually has nothing to do with a constructor because it doesnt matter if i create one or not Hopefully my problem and code is clear enough, if any confusion please do tell, Thankyou in advance :) -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/579700#579700] Start a new discussion in Javassist at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
