It looks like compass is reading the System property, java.io.tmpdir and eventually it gets passed into a File constructor call. App Engine doesn't have a temp directory (we don't allow the writing of any files to disk), so this system property is set to null. If you need to set this system property for compass, you can configure it in your appengine-web.xml.
