I google and found some explanations (thanks a T. Broyer again) in this thread. I paste the here the explanation:
The "invalid type signature for" message indicates that the object
used by the client is different than the one known to the server (at
compile-time, a checksum of the object's fields is computed and sent
along with the object's class in the RPC payload; the same checksum is
computed at runtime on the server and compared to the one received
from the client).
used by the client is different than the one known to the server (at
compile-time, a checksum of the object's fields is computed and sent
along with the object's class in the RPC payload; the same checksum is
computed at runtime on the server and compared to the one received
from the client).
Please read the details in thread, perhaps help to you.

I am not getting it always, after doing a gwtcompile i am getting it
sometimes even in dev server... I tried to deploy it in tomcat after
creating a war, that time the response returns from handler, but
doesn't reach the async call back ..
Previously i was getting serialization error in Arraylist , but now i
am getting only this, not sure what changed...
Note: I am not extending IsSerializable but just extending all my
objects with java.io.Serializable...
