We have done some further investigation of the issue.
The problem in the Jobs module is caused because it tries to create custom fields for the Documents module in the installation of the module. Then this module calls a method from the Fluent API which forces a restart of the application. With this restart the Sitefinity boot-strapper is run again and tries to go into the section for adding the route handlers.
With some new changes in the Sitefinity API restarts of the application should not be made in the installation of a module. The restart should be done by the system initializer. We are re-factoring the code in the sample module so that it does not restart the system when the module is being installed.
