A DESCRIPTION OF THE PROBLEM :
javac emits incorrect bytecode when an interface declares a static field that depends on a nested class, and the interface also defines a default method. This causes incorrect static initialization order at runtime, resulting in null values where a valid reference is expected.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
```
// File: MyIssue.java
public interface MyIssue {
    String schema = MyIssue.A.schema;

    // commenting out below method fixes the issue
    default void accept(String var1) {
    }

    final class A implements MyIssue {
        public static final String schema = new String("aa").trim();
    }
}
```
```
// File: Application.java
public class Application {
    public static void main(String[] args) {
        // Uncommenting this line fixes the issue by triggering MyIssue.<clinit>
        // System.out.println(MyIssue.schema);

        System.out.println(MyIssue.A.schema); // prints "aa"
        System.out.println(MyIssue.schema); // prints "null" (!!)
    }
}
```

javac -d out Application.java MyIssue.java
java -cp out Application



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
execution prints on stdout:
aa
aa
ACTUAL -
execution prints on stdout:
aa
null
