Not sure, I'm not designing this myself, I can ask. 

I guess if bundles were actually verified when restarting, that would really 
help at least, though, it looks to me that in terms of performance doing the 
check at runtime instead would be more efficient (and more secured obviously).

As for security, even if the signatures are checked at runtime, it should be 
easy to stop the bundle, refresh (unresolve), tamper with the jar and restart 
the bundle.  There's a good change the signatures check would be bypassed.
