java.util.List with generics fails with compiler error

[GoogleCodeExporter]

Reflection still doesn't work for a java.util.List with generics.

Error is in the generated com.gwtent.client.reflection.TypeOracle_Visitor:

public Object invoke(Object instance, String methodName, Object[] args)
throws MethodInvokeException {
        java.util.List content = (java.util.List)instance;
        if (args == null){
          args = new Object[]{};
        }
        if (methodName.equals("add")) {
          checkInvokeParams(methodName, 1, args);
          return Boolean.valueOf(content.add(((java.lang.Object)args[0])));
        } else if (methodName.equals("add")) {
          checkInvokeParams(methodName, 2, args);
          content.add((((Integer)args[0]).intValue()),
((java.lang.Object)args[1]));
          return null;
        }
        ........................
        .......................
        } else if (methodName.equals("toArray")) {
          checkInvokeParams(methodName, 1, args);
          return (Object)content.toArray(((T extends
java.lang.Object[])args[0]));
        } else return super.invoke(instance, methodName, args);
      }

The compiler fails here:

return (Object)content.toArray(((T extends java.lang.Object[])args[0]));

Hi, flavius, Thank you for let me know this issue

I can pass all my test case in my computer,
You can check this file to see is it your case.
gwtent\test\com\gwtent\client\test\reflection\TestReflection.java

The fixed issue is here: 
http://code.google.com/p/gwt-ent/issues/detail?id=3&can=1
Can you check with this.

And I uploaded my gwtent.jar as well, can you try with this jar?

If issues still there, can you send me your case?
thanks

The test fails with the same error.

BTW i'm using GWT 1.6M2. Did you get a change to test against it ?

This jar is built with java 6. Please rebuild with java 5, as per issue 4. :)

GWTShell does not work in java 6 on Macs.
