java - Eclipse 不会因我的插件而退出

Question

我正在开发自己的 Eclipse 插件，并遇到了一个非常奇怪的行为。在某些非常特殊的情况下，当我关闭工作台时，Eclipse 不会退出。它会一直挂着，直到我终止该进程。通过 PDE 运行以及作为常规安装运行时会发生这种情况。

确实很难提供更多细节，而且我知道这是一个非常普遍的问题。然而，我想知道是否有人遇到过这种行为并可以分享解决方案。

谢谢。兹维基

PS。我在工作台退出后附加所有正在运行的线程的堆栈跟踪。也许会弹出一些东西。此跟踪是通过在 Debug模式下运行 IDE、在卡住后挂起它并复制所有线程树来实现的。

抱歉打扰大家...有问题了。

我的问题很简单:我的一个操作处理程序在 Dispose 方法中引发了异常。这会导致整个工作区挂起。
