Summary of changes:

1. Removed the security manager test to verify methods throw when under the security manager and logging control is not granted. The only way to bring this test back is to create a test to run with custom log manager that overrides checkAccess. I don't think this is worth doing.
2. Removed 2 tests related to verifying a memory optimization around super error manager. This test doesn't really have anything to do with correctness so the loss of coverage is not a big deal.
3. Some of the existing SecurityManager test around the context class loader were updated to use a custom thread instead of a SecurityManager.
4. New method and tests were added to optionally invoke the AccessController if is still present. This only happens if permissions fail when attempting an operation without privileges.
5. Removed AccessController and SecurityManager from the demos
6. Removed ThreadDeath checks during unwrap of exceptions. ThreadDeath is now deprecated.
7. Replaced some of the argument checks with Objects.requireNonNull. I'll fix remaining ones in follow on tickets.

@lukasj

• MailHandler is missing cp year update

  • I prefer Objects.requireNonNull over if (x == null) throw new NPE (in LogManagerProperties) but that is a matter of taste

Fixed copywrite year. I updated the code to use requireNonNull. There is one case that is omitted because the argument is a Throwable which interestingly enough will trigger an IDE warning that return type of Throwable was not read. That method will be dealt with in a follow on ticket.

thanks!
