After upgrading the SDK from appengine-java-sdk-1.9.63 to appengine-java-sdk-1.9.64, I'm seeing a RuntimeException: "No permissions needed for this runtime." error when trying to access my application using the app engine dev server.

Providing a reproducible case is difficult; we're using Scala with the sbt-appengine plugin. I'm hoping that the problem is on our end, possibly that the sbt-appengine plugin needs to be updated for 1.9.64. However, I don't understand the conditions causing the "No permissions needed for this runtime" error. Can someone provide a hint as to why this might be happening?

In the mean time, I'm going to continue to try to further isolate the problem. Thanks.

Here's the stack trace:
