正如前面提到的那样，EJB组件控制着对后台数据的访问，并管理着当前事务和数据库的内部锁定。
As mentioned previously, the EJB components control the access to the back-end data and manage the current transactions and database locking internally.
但是，总的来说，问题依然存在：行为不良的组件能够使用并锁定一个进程的所有可用线程，即使您已经正确配置了隔离的线程池。
Overall, however, the concern remains that misbehaving components can use and lock all available threads for a process, even if you have properly configured isolated thread pools.
在创建新模式时，可以锁定模式中与组件有关的属性。
When creating a new pattern, you can lock properties associated with components in the pattern.
