这是在从Eclipse 3迁移代码时发生的。x到4.5火星，Java 6到Java 8。

Eclipse internals were substantially rewritten for Eclipse 4 and WorkbenchWindow is no longer derived from ApplicationWindow so you cannot do this cast. This was never really part of the defined API anyway.
Eclipse的内部组件已经为Eclipse 4进行了大量重写，而WorkbenchWindow不再从ApplicationWindow派生，因此您无法执行此转换。这从来都不是定义的API的一部分。
To get the cool bar manager use:
要得到cool bar manager的使用:
getWindowConfigurer().getActionBarConfigurer().getCoolBarManager();
