Java Records and Lombok annotation - IntelliJ

问题

Just trying a hands-on the java.lang.Record. I have gone through the documentation and the JEP-359 for some understanding. So upon reading about the implicit declaration of the constructor I thought of mixing it up with an existing code generation library - Lombok!

Now what I've ended up creating as a minimal reproducible example is this record

import lombok.AllArgsConstructor;

@AllArgsConstructor
public record Java(String version) {
}

which when compiled using IntelliJ successfully produces the class file which looks like

public final class Java extends java.lang.Record {
    private final java.lang.String version;
    public Java(java.lang.String version) { /* compiled code */ }
    ... rest of the compiled code
}

Note that the constructor for the .class file is just what I would have expected in the two worlds independently as well. But, further trying to create an instance of this record fails during compilation in IntelliJ :

public class MixOfWorlds {

    public static void main(String[] args) {
        System.out.println(new Java("14").version()); // cannot resolve constructor
    }
}

I would create a further simpler example to perform the compilation with javac and execution with java tools. I am still looking for an answer if this is a possible expected behavior that could occur because of something I might have overlooked?
