If you look at the Class.java that GWT uses to emulate the JVM's Class, you'll see that it does not implement Serializable.

Hi,

I have a class defined in a way similar to this:

class MyType<T extends MyGen>  extends Serializable {

    private Class<T>  aClass;

    public MyType() {}

    public void setClass(Class<T>  aClass) {
       this.aClass = aClass;
    }
}

where MyGen is also Serializable

When I compile de project (I'am currently still using GWT 2.1.0 RC1),
then I find the following :

1) the compiler (using the compiler options -extra, -work and -gen)
does not generate the code MyType_FieldSerializer.java as it does for
all other serializable classes.

2) In the "extra" / rpclog dir, the class MyType is flagged like this:
    Serialization status
       Not serializable

3) And when I run my app, I get an "InvocationException" : the client
is unable to make an RPC call with a parameter of type MyType.

Is it a bug in the compiler, or did I missed something about Class<T>
"serializability" ?

Thanks for your help
Yves
