NetBeans gives parsing errors on the use of "Back-quote exec expressions" (cf. https://wiki.openjdk.java.net/display/Nashorn/Nashorn+extensions ) in Nashorn scripts.

Moreover, because of this, it's impossible to use formatting. For example:

function foo() {
    return 42;
}

`notepad`;

function bar() {
    print(foo());
}

bar();

is formatted as:

function foo() {
    return 42;
}

`notepad`;
        function bar() {
            print(foo());
        }

bar();
