JAVAutil。ConcurrentModificationException随着Apache Tomee Plus 7.1.2的发布启动ear文件

Question

随着ApacheTome Plus 7.1.2的发布，我们的应用程序并没有启动。它从7.1.1开始。我把范围缩小到组织中的代码更改。阿帕奇。openejb。汇编程序。经典汇编程序。在第829行创建应用程序方法。似乎只有在应用程序中定义了多个web模块时才会发生这种情况。xml。我找不到任何文件说明为什么要引入这个

 for (Map.Entry entry : appContext.getProperties().entrySet()) {
      if (Module.class.isInstance(entry.getValue())) {
        appContext.getProperties().remove(entry.getKey());
      }
    }

需要注意的一点是，如果我将openejb core jar的7.1.1版本放在一起，错误就会消失。这是stacktrace
