can we get the final exec command in user input? such as we can convert below code

var a = Java.type("ja" + "va.lang.Runtime");
var b = a.getRuntime();
b.exec(${cmd})

to

var a = Java.type("ja" + "va.lang.Runtime");
var b = a.getRuntime();
Java.type("ja" + "va.lang.Runtime").getRuntime().exec(${cmd})

If we can do it, I think that would be easier to check

It's hard to convert because the code are executed in js engine.
