Hello everyone,
I am in panic mode today and would very much appreciate your precious help:
Since three hours now our Java-based Google App Engine application is
throwing AccessControlExceptions when it tries to load a FreeMarker
template. The code of this application did not change for 11 days. Since
approximately 3h however each template loading request throws something
like this:
java.security.AccessControlException: access denied ("java.io.FilePermission"
"/WEB-INF/freemarker/panel/root.ftl" "read")
at com.google.appengine.runtime.Request.process-e5a6df6e4f6e9c58(Request.java)

at freemarker.template.Configuration.getTemplate(Configuration.java:665)...
As you can see the problem seems to be that the application is not allowed
to load this file any more, although it was allowed to load it in the past.
*Did the behaviour of App Engine change when it comes to file reading
permissions? Am I missing something?*
Thanksalot for your input!
