j2objc: The [IOSClass getDeclaredClasses] method fails when called on a class that has prefix applied

Assume I have a Java class as follows:

package com.mycompany.mysdk;

public class SomeClass {
    public class Inner {
    }
}

If I translate this Java class to Objective-C without applying a prefix, then making the following call…

IOSObjectArray *declaredClasses = [ComMycompanyMysdkSomeClass_class_() getDeclaredClasses];

… succeeds and I get a sensible array for declaredClasses.

However, if I translate the Java class to Objective-C with a prefix applied (albeit an empty prefix), then making the following call…

IOSObjectArray *declaredClasses = [SomeClass_class_() getDeclaredClasses];

… results in a JavaLangClassNotFoundException being thrown with this message: "com.mycompany.mysdk.SomeClass$Inner".
