jsp sesson范围内的Wildfly 10 bean需要可序列化吗？

Question

我将一堆Web应用程序从JBoss 4.2.2迁移到Wildfly10。对于Wildfly 10，我使用独立模式，并使用会话共享功能，因此所有war文件都在同一耳朵下。

我有一个带一行的jsp文件

 <jsp:useBean id="session_counter" class="com.count.CounterBean" scope="session" />

[当我尝试访问此页面时，出现NotSerializableException错误。我没有使用集群，也没有EJB。我试图从standalone.xml中禁用以下配置，它不起作用。

<cache name="distributable" passivation-store-ref="infinispan" aliases="passivating clustered"/>

我只需要一个Java对象进入会话范围，是否需要实现Serializable接口？我试图避免更改代码。有谁知道任何配置或解决此问题？

以下是堆栈跟踪：
