mountByFS does not work

[Sandro Boehme]

Hello,

in my case a FS mount (-Dsling.mountByFS=true) does not work.
The configMgr of the web console shows that the mount is there and 
FileMonitor.check() detects the change and sends the event.
My question is: Who is the receiver of the event? I understand that it's 
the event of the FsResourceProvider but what code listens to the change 
and (in my case) doesn't promote it.

Thanks,

Sandro
