RFR: 8170602: Startup regression due to introduction of lambda in java.io.FilePermissionCollection

[Claes Redestad]

Hi,

recent changes to FilePermissionCollection to use a lambda in place of 
an explicit
BiFunction cause a quite noticeable startup and footprint regression on 
small
applications due to a bootstrap dependency. Therefore I'd like to revert 
this
particular change.

Thanks!
