IncompatibleClassChangeError java8

Question

我在运行时遇到IncompatibleClassChangeError。我还没弄清楚原因。这是日志：

java.lang.IncompatibleClassChangeError
    at com.EmailCreator.lambda$null$396(EmailCreator.java:214)
    at com.EmailCreator$$Lambda$248/280771231.accept(Unknown Source)

代码：

private static class EmailReceiver {
    String email;
    String key;
    String list;

    public EmailReceiver(Subscriber subscriber, ExactTargetSubscriberList list) {
        this.email = subscriber.getEmail();
        this.key = subscriber.getState().getId().toString();
        this.list = list.getState().getId().toString();
    }
}

EmailCreator中的第214行就像subscriber.child（“EmailAddress”）。text（receiver.email）;来自以下代码。

        for (EmailReceiver receiver : receivers) {
            objects.child("Subscribers", subscribers -> {
                ETSoapBuilder.addNilFields(subscribers);
                subscribers.child("EmailAddress").text(receiver.email);
                subscribers.child("SubscriberKey").text(receiver.key);
                subscribers.child("Attributes", attributes -> {
                    attributes.child("Name").text("ContentID");
                    attributes.child("Value").text(email.getId().toString());
                });
                subscribers.child("Attributes", attributes -> {
                    attributes.child("Name").text("Hash");
                    attributes.child("Value").text(receiver.list);
                });
                subscribers.child("Attributes", attributes -> {
                    attributes.child("Name").text("SubscriberKey");
                    attributes.child("Value").text(receiver.key);
                });
                subscribers.child("Attributes", attributes -> {
                    attributes.child("Name").text("EmailAddress");
                    attributes.child("Value").text(receiver.email);
                });
            });
        }
    });

非常感谢任何帮助!!
