我可以使用PrimeFaces 6.0展示重现异常，因此看来原因不在我的代码中。
这是用PrimeFaces展示的如何复制的方法：
下载PrimeFaces 6.0从Github出发。
向
pom.xml添加一个Onmifaces依赖关系：<dependency> <groupId>org.omnifaces</groupId> <artifactId>omnifaces</artifactId> <version>2.3</version> </dependency>从http://blog.payara.fish.fish/creating-uber-jar-jar-with-payara-micro添加Payara Micro Uber Jar创建的Maven代码
使用
mvn package构建，然后从java -jar showcase-6.0.jar
开始现在，在Local主机上启动展示柜，然后打开数据表懒负载示例，您应该获得异常。
当删除综合依赖性时，不会发生exeption。并且它不是在Payara应用程序服务器上发生的，而是在Payara Micro。
上发生。所以我不确定错误是否在omnifaces，payara micro，primefaces或任何地方。
此行为是由<distributable>标志引起的，该标志已添加到Omnifaces 2.1中，以支持在集群上运行。
这反过来又发现了PrimeFaces 6.0中的一些错误，PrimeFaces Showcase应用程序和Payara Micro。
- PrimeFaces 6.0新的
PhaseInfo类实现Serializable，但具有PhaseId属性，该属性根本不是Serializable。 - 在PrimeFaces展示中，有几个
Serializable查看范围的bean，具有不可隔离的服务属性，例如CarService中的CC_11在LazyView中备份Bean在懒惰数据表演示页面后面的bean。 - Payara Micro似乎不考虑战争自己的
web.xml是否具有<distributable>标志集。如果未设置此标志，则容器不应将战争视为可分配的。
当您完全删除Ommnifaces时，PrimeFaces 6.0和PrimeFaces展示柜的序列化问题是可重现的，但是在PrimeFaces Showcase的web.xml中设置<distributable>标志。这些问题中的每一个都需要单独报告。我至少报告了PhaseInfo问题为第1570期，并在您的Payara Micro问题上发表了评论。
在稍微相关的说明上，我还注意到PrimeFaces Showcase的web.xml已将Mojarra特定的com.sun.faces.serializeServerState设置为pom.xml0。我尚未调查回到true时的效果，但是false的这种设置是不推荐的，因为它可能隐藏了与查看构建和状态管理有关的其他错误。
