Hi Martin, For some reason, a proxied bean's equals cannot be called. Are you aware of this problem? Although the spec says: The behavior of all methods declared by java.lang.Object, except for toString(), is undefined for a client proxy. Portable applications should not invoke any method declared by java.lang.Object, except for toString(), on a client proxy. I thought the overridden equals is different from the methods defined by Object class and it should be invoked. Please find attached a very simple test case that shows a .equals() method not being invoked on a bean proxied by Weld. In a debugger one can see that GenericBean.equals() is not invoked within the Servlet: protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { PrintWriter pw = response.getWriter(); pw.println ("Hello"); if (gb.equals(new GenericBean(10))) { // GenericBean.equals() is not invoked; test prints 'fail' pw.println("pass"); } else { pw.println ("fail"); } } The .war contains source and object code. As you can see there's only two classes.
