RFR: 8224589: Improve startup behavior of SecurityProperties

[Claes Redestad]

Hi,

some recent security features have been pushing initialization of
sun.security.util.SecurityProperties to happen earlier in the
bootstrap sequence, which is affecting startup timings on a few
targetted applications.

This patch helps by desugaring potentially early bootstrap lambda use,
and further keep the impact more neutral in cases where no 
SecurityManager is installed.
