Re: GWT 2.6.0, SuperDevMode, and GWT-RPC serialization error

I thought of that since I recall something similar going from 2.4 to 2.5 (or some such upgrade). I cleared my browser cache completely and (as I said) called `mvn clean` to remove target. I also removed the www-test and gwt-unitCache directories. I even did a clean on supporting libraries. Is there something else I should zap?

Seems a cache error. Did you clean all temp data?

I have switched over a new project to GWT 2.6.0. I running with Maven and the GWT Maven Plugin 2.6.0-rc3.

Everything was working swimmingly with GWT 2.5.1. Now I'm getting GWT-RPC serialization errors when running SuperDevMode.

If I start DevMode from Maven (gwt:run) or through Eclipse, the classes that I have marked as implementing java.io.Serializable pass through the RPC layer without a hitch. However, serialization fails with SuperDevMode:
 
- start SuperDevMode from a console with Maven and gwt:run-codeserver)
- start the server though Eclipse in Development Mode
- turn Dev Mode On and Compile

Now executing the GWT-RPC method shows this in my console file:

Starting Jetty on port 8888

If I implement AboutBoxData with com.google.gwt.user.client.rpc.IsSerializable vs java.io.Serializable, the class will eventually fail because of a member that uses java.io.Serializable.

What could be causing this? I've cleaned my Maven tree down to pom.xml and src, but each time I get this error. 

Is there some new setting to gwt-maven-plugin?

Is there some Eclipse plugin I should|should not be running? My Eclipse has installed m2e from http://download.eclipse.org/technology/m2e/releases/ and m2e-apt and m2e-wtp from http://download.jboss.org/jbosstools/updates/...   I have removed the Jetty plugins I was using elsewhere.

Thanks for y'all's help. I want to run 2.6.0 because I want to work with the latest MGWT SNAPSHOTS as they are available, and I don't want to give up SuperDevMode.
