Wrong highlighting on 'new' keyword on inner classes

[Eskibear]

Description

creating a new instance of an inner class doesn't highlight the new keyword properly

inner

Steps to Reproduce

public class Foo {
    public class Bar {
    }
}

public class Main {
    public static void main(String[] args) {
        Foo example1 = new Foo();
        Foo.Bar example2 = example1.new Bar();   // <----
    }
}

Expected behavior:

keyword new is correctly highlighted.

Actual behavior:

The code does not compile, not an issue.

It compiles.

Is that OpenJDK 14? I compile on JDK 8, which is what we keep as a baseline. This is a new feature then. Please update the issue accordingly.

Also, shouldn't it be like this?

Foo.Bar example2 = new example1.Bar();   // <----

See https://docs.oracle.com/javase/tutorial/java/javaOO/nested.html , section "Inner Classes".

To instantiate an inner class, you must first instantiate the outer class. Then, create the inner object within the outer object with this syntax:

OuterClass.InnerClass innerObject = outerObject.new InnerClass()

It's strange, and I don't know why new example1.Bar() compiles for you. It doesn't compiles for me, with either JDK 8 or 14.

Yeah, I came up with a working example, similar to your code. Looks like a bug.
