RFR: 8202419: Avoid creating Permission constants early

[Claes Redestad]

Hi,

moving a couple of local permission constants to 
sun.security.util.SecurityConstants ensures we delay and avoid loading 
permission classes very early during bootstrap. Delaying load is 
profitable since it's happening early enough (before System.initPhase1) 
to contribute to delaying the initialization of VM subsystems.

Thanks!
