Gradle Javadoc任务在Java 10中失败

Question

尝试在我的gradle构建中执行javadoc任务时，将打印出以下消息（以及我可以应要求提供的堆栈跟踪）：

javadoc: error - An internal exception has occurred. 
    (com.sun.tools.javac.code.ClassFinder$BadClassFile: bad class file: /home/vtcakavsmoace/IdeaProjects/DiscordSRV2-Core/build/classes/java/main/com/discordsrv/core/auth/PlayerUserAuthenticator$1$1.class
  bad enclosing class for com.discordsrv.core.auth.PlayerUserAuthenticator$1$1: com.discordsrv.core.auth.PlayerUserAuthenticator$1
  Please remove or make sure it appears in the correct subdirectory of the classpath.)
Please file a bug against the javadoc tool via the Java bug reporting page
(http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com)
for duplicates. Include error messages and the following diagnostic in your report. Thank you.

javadoc似乎正在尝试记录匿名内部类的匿名内部类。

在build文件夹中进行进一步检查时，您可以看到该匿名类根本不存在：

这是文件中唯一包含匿名类的方法（为清楚起见已简化）：

public void doSomething() {
    map.forEach((key, value) -> key.doSomething(response -> {
            invokeWithCallback(value, var, new FutureCallback<Boolean>() {
                @Override
                public void onSuccess(final @Nullable Boolean result) {
                    ...
                    new Pair<Key, Value>() {
                        ...
                    }
                    ...
                }

                @Override
                public void onFailure(final @Nonnull Throwable t) {
                    ...
                }
            });
        }
    }));
}

我应该如何处理以确保javadoc任务可以完成？

编辑：

多做一些探索；删除内部匿名类可以完成javadoc任务，因此这个匿名实例似乎是问题所在。

解决方法：

声明一个内部类，在其中执行匿名实例化。这样可以防止javadoc尝试解析不存在的类文件。以问题的格式：

public void doSomething() {
    map.forEach((key, value) -> key.doSomething(response -> {
            invokeWithCallback(value, var, new MyCallback(...));
        }
    }));
}

private class MyCallback implements FutureCallback<Boolean> {

    ...

    @Override
    public void onSuccess(final @Nullable Boolean result) {
        ...
        new Pair<Key, Value>() {
            ...
        }
        ...
    }

    ...

}

话虽这么说，我很快就会向Java提交更正式的错误报告。
