Ambiguous call to String.replace() on java.lang.Strings

I was trying to use the following code:

var s = escape(args["a"]);

function escape(s) {
  return s.replace(/[\\]/g, "\\\\").replace(/[\"]/g, "\\\"");
}‍‍‍‍‍

This is a fairly simple usecase, but I was getting the following error:

The choice of Java constructor replace matching JavaScript argument types (function,string) is ambiguous; candidate constructors are: class java.lang.String replace(char,char); class java.lang.String replace(java.lang.CharSequence,java.lang.CharSequence)

This didn't make any sense to me, until I realised that it looks like Alfresco Javascript has TWO Strings: java.lang.Strings and "Javascript" strings.

A workaround is to "cast" it to a "Javascript" string as follows:

function escape(s) {
  return (s + "").replace(/[\\]/g, "\\\\").replace(/[\"]/g, "\\\"");
}‍‍‍

Is this intended behaviour?

this is Alfresco java script,by default it will treat string object as java string object.
most of the times things will be more similar to java then javascript in alfresco javascript.
