Hi,

I'm trying to finalize our development environment for Javascript, and I
would like to integrate Closure Compiler into the process.
My idea was to invoke the compiler from a servlet, that is served by
Google App Engine in the development environment.
Certainly I don't want to use this feature in the actual release, I
would just use the precompiled version.
But when I try to invoke the compiler, I get an Access Control
Exception. Here is the relevant part of the exception:

java.security.AccessControlException: access denied
(java.lang.RuntimePermission modifyThreadGroup)
at
java.security.AccessControlContext.checkPermission(AccessControlContext.java:323)

java.security.AccessController.checkPermission(AccessController.java:546)

Is there a way, to use the compiler without threads? Has anyone tried to
use the compiler this way?
Does anybody know a way to disable this specific restriction form the
App Engine on localhost?

Best regards,
Peter Balogh
