When you launch a template in that dummy environment, does that run in
its own JVM, or at least does it have its own class-loader for
freemarker.jar? Because then you could just set the
DebuggerServiceSingleton.setInstance(), yet only affect that running
application. Otherwise we got a problem without setting it in the
configuration. Maybe we could use TLS. So you could have:

   DebuggerService prev = DebuggerServiceSingleton.setThreadLocalInstance(myDebuggerService);
   try {
       ...
       Do whatever you want here, like even with multiple
       Configuration-s.
       DebuggerServiceSingleton.getInstance() will return the instance
       from the TLS now.
       ...
   } finally {
       DebuggerServiceSingleton.setThreadLocalInstance(prev);
   }

Would that work?
