I'm using

• OSX 10.9.5
• java version "1.8.0_25"
  Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
  Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
• appengine-java-sdk-1.9.15/
• [appengine-magic "0.5.1-SNAPSHOT"]

[gcv]

I stopped using Google App Engine some time ago, and don't have time to support recent versions. 0.5.1-SNAPSHOT is not fully functional, and the 1.9.15 release from Google is definitely not supported. If you want anything to work, you have to use appengine-magic version 0.5.0 and Google's release 1.6.3.1.

[tangrammer]

Thanks for your answer but,
I spent a few hours trying to get working, wondering if the reason could be java or appengine-sdk version ... :(
why don't you specify working versions in the README?

[gcv]

The Current Status section of the README specifies working versions. It also notes that 0.5.1-SNAPSHOT is unstable, and that you should use 0.5.0.
