A DESCRIPTION OF THE PROBLEM :
When using javac "enable-preview" along with "debug" flag, the output class seems borked.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
javac --enable-preview --release 21 -g org/example/Main.java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
$ java --enable-preview org.example.Main
Hello, World!
Hello, World!
Hello, World!

ACTUAL -
$ java --enable-preview org.example.Main
Error: LinkageError occurred while loading main class org.example.Main
java.lang.ClassFormatError: Illegal field name "" in class org/example/Main


---------- BEGIN SOURCE ----------
package org.example;

import java.util.List;

public class Main {
    public static void main(String[] args) {
        for (var _ : List.of(1, 2, 3)) {
            System.out.println("Hello, World!");
        }
    }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Do not specify --enable-prefix and -g together. Note: maven compiler plugin BY DEFAULT sets javac -g flag (debug).


FREQUENCY : always
