我们已经将我们的企业软件从 Java 7 迁移到 Java 8，并且随之将 Spring 更新到了 4.3.4 版本。从那时起，部署失败，因为由于 StackOverflowError 无法初始化 bean 之一：

Caused By: java.lang.StackOverflowError
    at org.springframework.scheduling.commonj.WorkManagerTaskExecutor.schedule(WorkManagerTaskExecutor.java:204)
    at org.springframework.scheduling.commonj.WorkManagerTaskExecutor.schedule(WorkManagerTaskExecutor.java:204)
    at org.springframework.scheduling.commonj.WorkManagerTaskExecutor.schedule(WorkManagerTaskExecutor.java:204)
    at org.springframework.scheduling.commonj.WorkManagerTaskExecutor.schedule(WorkManagerTaskExecutor.java:204)
    at org.springframework.scheduling.commonj.WorkManagerTaskExecutor.schedule(WorkManagerTaskExecutor.java:204)
    at org.springframework.scheduling.commonj.WorkManagerTaskExecutor.schedule(WorkManagerTaskExecutor.java:204)
    at org.springframework.scheduling.commonj.WorkManagerTaskExecutor.schedule(WorkManagerTaskExecutor.java:204)
    at org.springframework.scheduling.commonj.WorkManagerTaskExecutor.schedule(WorkManagerTaskExecutor.java:204)
    at org.springframework.scheduling.commonj.WorkManagerTaskExecutor.schedule(WorkManagerTaskExecutor.java:204)
    at org.springframework.scheduling.commonj.WorkManagerTaskExecutor.schedule(WorkManagerTaskExecutor.java:204)
    at org.springframework.scheduling.commonj.WorkManagerTaskExecutor.schedule(WorkManagerTaskExecutor.java:204)

如您所见，方法 schedule() 被递归调用，导致堆栈溢出。该应用程序部署在 Weblogic 12.1.3 版本上；这是来自 WorkManagerTaskExecutor.schedule() 的代码片段：

return this.workManager.schedule(work);

所以这应该将调度调用委托给目标 WorkManager 对象。然而，根据我们的调试分析，WorkManagerTaskExecutor内部的私有成员workManager已被初始化为WorkManagerTaskExecutor类型的实例，即this.workManager.schedule(work); 执行时，它正在调用WorkManagerTaskExecutor.schedule()，导致递归调用。

Weblogic 的目标 WorkManager 在部署描述符中设置如下： ...

<resource-ref>
            <res-ref-name>wm/MyWorkManager</res-ref-name>
            <res-type>commonj.work.WorkManager</res-type>
            <res-auth>Container</res-auth>
            <res-sharing-scope>Shareable</res-sharing-scope>
        </resource-ref>

...

<work-manager>
    <name>wm/ODSCacheWorkManager</name>
    <max-threads-constraint>
        <name>MaxThreads</name>
        <count>1</count>
    </max-threads-constraint>
    <ignore-stuck-threads>true</ignore-stuck-threads>
</work-manager>

...

在 Spring 应用程序上下文中：

<bean autowire="byType" id="taskExecutor" class="org.springframework.scheduling.commonj.WorkManagerTaskExecutor">
            <property name="workManagerName" value="java:comp/env/wm/MyWorkManager"/>
            <property name="resourceRef" value="true"/>
        </bean>

为什么WorkManagerTaskExecutor 中的 workManager 再次用 WorkManagerTaskExecutor的实例初始化，导致递归，我们严重想不通。社区能帮忙吗？
