I'm trying to call a method with arguments that might need autoboxing. But I'm getting the following error: Caused by: compile error: f(org.p.test.main.AA,int,int) not found in org.p.MyClass at javassist.compiler.TypeChecker.atMethodCallCore(TypeChecker.java:716) at javassist.compiler.TypeChecker.atCallExpr(TypeChecker.java:682) when I tried to cast the int to Object I got the following error: Caused by: compile error: invalid cast at javassist.compiler.CodeGen.checkCastExpr(CodeGen.java:1397) at javassist.compiler.CodeGen.atCastExpr(CodeGen.java:1363) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4138432#...
