As shown in JDK-8023122 subsequent failed class resolution attempts have different detail messages:

$ cat ExtTest.java
class ExtTest {
    public static void main(String args[]) {
try {
Property p = new Property();
} catch (NoClassDefFoundError e) {
System.out.println(e);
}
try {
Property p = new Property();
} catch (NoClassDefFoundError e) {
System.out.println(e);
}
    }
}

$ java -Xint ExtTest
java.lang.NoClassDefFoundError: PropertyChild
java.lang.NoClassDefFoundError: Property

The fix would be to report the to-be resolved class in the initial exception as well:
