Java 如果零件从区域内的零件堆栈关闭，则引发异常

我有基于兼容层的RCP应用程序。 在UI中，我有一个区域（包含部件堆栈），如下图所示

我创建了一个在上面区域打开的零件，请参见下文。

现在的问题是当我关闭我的部分，部分正在关闭，但我得到以下异常

其工作原理（以下情况无例外）：

若我删除区域并只使用PartStack，那个么它可以工作，我不会得到任何异常

即使在我的应用程序中，我也在重用JSDT透视图，如果我在JSDT的编辑器区域中打开相同的部分，并且如果我关闭它，那么它也可以工作（没有例外）

是我缺少的东西。

MArea是在Eclipse 4中支持共享“编辑器”区域的情况下实现的，在其他用途中可能有一些逻辑漏洞，特别是在没有透视图的情况下（是这样吗？）。

听起来与Eclipse bug类似
