`this.` are not needed

This call may throw CompletionException instead of PrivilegedActionException
That's strange that this case does not go through standard
`doPrivilegedOperation` way.
I think this class needs to be improved (most likely as a separate PR).
For most of operations it created "operation id" and creates array of
arguments, but then `doOperation` parses the id and arguments and performs
required action. It would be much simpler if doPrivilegedOperation/doOperation
accept Callable.

Suggestion:
if (e instanceof SecurityException se) {
throw se;

Suggestion:
} else if (e instanceof Exception e1) {
throw new PrivilegedActionException(e1);

Need to handle CompletionException (or maybe at Subject.callAs call)?
