appengine NullPointerException: Method name is null on application startup

[Luis Angel Cano via StackOverflow]

Since yesterday my application is getting the following error on all requests on the Google App Engine

Uncaught exception from servlet

No changes have been made to the code and it was working fine, it works fine on the developer server, it tried to reupdate the application and still getting the same message.

Appengine SDK version: 1.9.40
