Fixes #6184 - JEP-411 will deprecate/remove the SecurityManager from … (
#9616) * Fixes #6184 - JEP-411 will deprecate/remove the SecurityManager from the JVM. Removed usages of `SecurityManager` and `AccessControlller.doPrivileged()`. In places where they are still necessary, now using reflection via newly introduced `SecurityUtils` class. Signed-off-by: Simone Bordet <[email protected]>
