Description
Consider the following script:

#!/usr/bin/jjs -J-Dnashorn.args=-strict -scripting -fv
print('Hello');

When executed without arguments, prints Nashorn full version string.
When executed with arguments, does not print version string.

$> ./temp.js 
nashorn full version 1.8.0_45-b14
Hello
$> ./temp.js -- 
Hello
$> ./tem.js -- foobar
Hello

Parameters are being ignored (-strict, -ot, -doe, etc...) when arguments are passed.
Comments
Problem is that Options.process method stops at first "--" and treats everything after that as script arguments. But then "nashorn.args" is processed after processing user supplied args! This implies that if there are user supplied script arguments, nashorn.args System property is not processed at all! (as System property) So fix is to avoid adding all arguments to the same list (nashorn.args.prepend, nashorn.args and user supplied arguments) - instead each has to be processed separately.

Even without using shebang executable, the same problem can be reproduced. For example, no error for the following => -strict mode is not effective jjs -J-Dnashorn.args=-strict -- arg1 arg2 jjs> eval = 23; Whereas we get error when using this: jjs -J-Dnashorn.args=-strict jjs> eval = 23;
