Karl Pauls commented on FELIX-3610:
-----------------------------------

I guess I'm not sure what you are saying. Basically, everytime a bundle is 
installed or reloaded we verify its signatures on all its entries.  Not only 
when it is installed the first time. 

Doing a check everytime an entry is loaded from the jar doesn't make much sense 
to me. We verified the entries already - why do it again? 

The only reason I can see would be that you don't trust your own cache (i.e., 
somebody could manipulate entries inside the cache while the framework is 
running) and in that case, all bets are off anyways. Besides, It'd be teribble 
slow too, I imagine.

> Signed bundles are only checked when installed, but the goal of signed
