I both of the following classes are stored in a static CDS archive, the "xxxx123yyyy456" string is not stored in the interned string table. As a result, the test will fail with the RuntimeException

public super class OldClassWithStaticString
    version 49:0
{
    public static final Field s:"Ljava/lang/String;" = String "xxxx123yyyy456";
    public static final Field t:"Ljava/lang/String;" = String "OldClassWithStaticString";

    Method "<init>":"()V"
        stack 1 locals 1
    {
        aload_0;
        invokespecial Method java/lang/Object."<init>":"()V";
        return;
    }
}

class StaticStringInOldClassApp {
    static String a = "xxxx123";
    public static void main(String args[]) throws Exception {
        System.out.println("Hello");
        String x = (a + "yyyy456").intern();
        Class c = OldClassWithStaticString.class;
        Field f = c.getField("s");
        String y = (String)(f.get(null));
        if (x != y) {
            throw new RuntimeException("Interned strings not equal: " +
                                       "\"" + x + "\" @ " + System.identityHashCode(x) + " vs " +
                                       "\"" + y + "\" @ " + System.identityHashCode(y));
        }
    }
}
