String comparing problem

[SavchenkoVV]

'name' === 'name' // true
String('name') === String('name') // false

Why wrapped strings not equals ?
And how it possible to use switch operator with java string?

Most likely due to how you've configured Rhino, see #247 (comment)

Thanks for replying.
Tried with the setJavaPrimitiveWrap setting (true/false) - no changes in my case.

How are you getting your Java String instances then?

[SavchenkoVV]

By call lambda, but it is not important. Problem in comparing wrapped strings

String('name') === String('name') // false

Well, depending on the setJavaPrimitiveWrap setting they ought to be wrapped as Native JavaScript strings or not. When they are JavaScript strings, String('name') === String('name') should yield true, but if they are Java String instances it's imho expected that String('name') === String('name') yields false, as it would in Java because you're comparing instances.

I tested setJavaPrimitiveWrap with true and false.
Always String('name') === String('name') // false
Maybe i do something wrong...

As i understand switch operator use === to compare in cases.
So, if yot have string param v and do

switch(String(v).toLowerCase()) {
}

no one case will work.
May be it releted with #891

Without having some sample code that reproduces the issue, there's no telling whether this is expected behavior, a bug or whether you're doing something wrong

Tried new java.lang.String('name').length() && new java.lang.String('name') !== new java.lang.String('name') && String(new java.lang.String('name')) === String(new java.lang.String('name')) but yields true as expected.

This code shows that:

1. a JavaString is not wrapped (as it has a .length() method (Java), instead of .length property (JavaScript)
2. comparing to Java String instances returns false
3. comparing to Java String instances wrapped in a JavaScript string returns true

So afaics all works as expected. As no sample code has been provided that reproduces the issue, I'm closing this issue

Feel free to reopen with a testcode reproducing the issue
