无法打开编辑器：引发了意外的异常

我当时在使用Eclipse的插件，现在突然间我无法再打开BPEL工作流。我得到这个错误无法打开编辑器：引发了意外的异常

对于初学者来说，这是一个'IllegalArgumentException'，所以某些方法会传递错误的参数。 – emlai 2015-02-07 20:08:19

这个堆栈给出了关于这种情况发生在哪种方法的任何线索？ – sakal 2015-02-07 20:17:11

顶部的那个。不知道为什么。 – emlai 2015-02-07 20:19:00

您的命令行参数的那部分看起来有点玄乎到me

...我为该插件启动自托管会话，并创建工作区运行时 - EclipseApplication – sakal 2015-02-07 20:39:10

查看ReplaceableUCharacterIterator的源代码，它在其构造函数中传入null时会抛出IllegalArgumentException。所以，失去了一些东西。可能是插件中的一个错误。可能是文件被删除了，而这些文件本来不应该存在，或者在上次会话中没有正确保存。或许多其他可能性。

最好的事情可能是创建一个新的工作区，并开始复制东西 - 这通常会解决eclipse/plugins问题，这些问题不值得花时间详细研究。

好吧，我确实创建了一个新的工作区，并且我复制了所有内容,,,,问题似乎在其他地方 – sakal 2015-02-08 01:59:36
