Is the `Security` class loaded and have the properties always been populated at
this point? ProtectionDomain` doesn't reference the `Security` class AFAICT.

The other security related events are not enabled by default. Is this one
enabled because it is only generated once? It seems it may still have some
startup overhead because AFAIU it forces a load of security properties even if
they are never accessed? Perhaps I don't fully understand how this event works
though.
