> When deploying a WAR which contains a JAX-RS resource class which is declaring  a locator that is supposed to return the resource class itself - i.e. {{this}} - the depoyment fails with a {{StackOverflowError}}.
> The annotation scanner loops until the stack overflow happens because it tries to process the JAX-RS resource class recursively and maybe the process tself should be protected against this case.
> The following stack trace represents the output of a deployment failure when an attempt to deploy a WAR with such a resource:
