GWT failed to get serialization policy

Question

When I deploy a new version of my GWT application, sometimes I get a log error:

SEVERE: GwtRpcEventSrvc: WARNING: Failed to get the SerializationPolicy 'www.host.com:22041/MYAPP/'; a legacy, 1.3.3 compatible, serialization policy will be 
 a result.                                                                      

• Question 1) Is there a problem with serialization policy files in the browser cache?
• Question 2) How to prevent such a log message? I tried adding changes to the request URL of the nocache.js ( <script src="MyApp.nocache.js?v=123"...) parameter , but that did not help.

Answer 1

Try clearing your browser cache . This worked for me .. after searching many ways to solve it.
