【问题描述】：
我有一个应用程序，其中客户端组件在“托管”环境中运行（作为 Adobe InDesign 插件）。在这种“托管”环境中，似乎不可能在执行期间创建线程，而只能在应用程序启动时创建。
这个客户端组件通过 JNDI 和 RMI/IIOP 连接到 Glassfish 服务器，以执行各种 EJB 方法调用，所有这些都可以完美运行（除了一些在这里不重要的繁琐CORBA serialization issues）。我想让它也使用 JMS 连接，以执行一些主题阅读。我用来执行这些主题阅读的代码已经在单元测试中，确保它可以启动、阅读主题并执行所需的集成（这更像是一个集成测试而不是单元测试，但我必须确定我的应用程序通信层，不是吗？）。这段代码在单元测试中运行时可以完美运行。不幸的是，当从我的客户端组件（嵌入在 Indesign 中，并且无法创建线程）运行时，它会以 NullPointerException 以下方式失败：

从我目前发现的情况来看，客户端代码获得了到 JMS 服务器的连接（连接到 mq://localhost://7676），但随后无法启动 TransactionList。未编译的源代码（感谢 Jad！）表明它在那里失败了：
/* 182*/Globals.getClusterManager().addEventListener(((ClusterListener) (this)));
尝试调试时，我还发现我的客户端无法启动org.glassfish.enterprise.iiop.util.S1ASThreadPoolManager，因为同样无法创建线程。
我猜有些地方出了问题，但是什么？我不知道。
那么，我如何告诉 glassfish 客户端环境线程只能从我的个人线程池（在应用程序启动时创建）中获取，而不是尝试创建自己的线程池并惨遭失败？
