License enforcement for Subscriber access and related features is described 
here: 

http://www.juniper.net/techpubs/software/junos/junos92/swconfig-install/license-enforcement.html#jN12F73

and, as far as I can understand, if you are not abused by warning messages
on commit and not requesting official support for licenseable features - 
you can use licenseable features even after grace period... 

At least for now...

Sometimes that may change - f.e., J-Flow and Andvanced BGP (route-reflection)
licenses were not enforced for J-Series for before JunOS 8.5, and enforcement 
of them were clearly outlined in release notes: 

 From JUNOS Release 8.5 onwards, if you have not installed a 
valid license, the BGP router reflectors and J-Flow traffic 
analysis features do not function.
