cleanup: cleanup usage of getSecurityManager()

BradWalker · BradWalker · commit e9d63654ce91 · 2026-01-27T21:08:03.000-07:00
desc: getSecurityManager() is deprecated and marked for imminent removal. In addition as of JDK 24, getSecurityManager() returns null.

This change removes getSecurityManager() from various places that have minimal impact.
