Netbeans保存挂起

我有一个编辑器TopComponent实现。出于某种原因，当我保存文档时，会引发错误。下面列出的是错误。我不确定从这个例外开始。你能分享你所知道的吗？感谢Netbeans保存挂起

EDIT 1

我有DataObject中且具有构造成一个新的MIME类型text/x-puml一个VisualElement子类。一旦我将这些改回text/plain，事情就开始奏效。我搜索了text/plain，看看我是否错过了更改text/x-puml的任何内容，但找不到任何内容。有没有其他的事情我应该改变MIME类型为text/x-puml？

EDIT 2

似乎现在零星发生，但往往不是发生。如果我有自定义MIME类型，是否需要实现自己的SaveCookie或Savable？

stacktrace中的哪一行包含您编写或编辑的类？ – 2013-05-11 21:55:47

这是有趣的部分，没有一行提到我的代码。但是我刚才确实发现了什么导致了这个问题。我有一个新的MIME类型的注册'text/x-puml'，一旦我将它改为'text/plain'，问题就消失了。你会碰巧知道我是否缺少任何配置。 – ShaggyInjun 2013-05-11 22:04:36

我还没有在NetBeans中使用自定义MIME类型，所以我无法在那里帮你。 – 2013-05-13 00:06:39

它看起来像一个信号灯问题。

系统无法保存文件，因为该文件上存在排他锁。另一个独占锁（根据保存需要）是不可能的。

试着看文件处理。某处必须是锁。

我有一个类似的错误，由于重命名，这是因为该文件的锁。所以我用了file's锁定与primaryFile.lock()在：

WindowManager.getDefault().invokeWhenUIReady(new Runnable() 
{ 
    @Override 
    public void run() 
    { 
     if (obj.getDomainModel() != null) 
     { 
      String newName = obj.getDomainModel().getName(); 
      FileObject primaryFile = obj.getPrimaryFile(); 
      try 
      { 
       primaryFile.rename(primaryFile.lock(), newName, primaryFile.getExt()); 
       callback.updateTitle(newName); 
      } 
      catch (IOException ex) 
      { 
       String message = String.format("The model couldn´t be renamed to \"%s\"", newName); 

       LOG.warning(message); 
      } 
     } 
    } 
});

用它来保存文件或相似任何情况下。

我的例子我有同样的问题，但重命名，而不是保存。但同样的问题：先前打开的文件的锁定。 – EliuX 2015-08-27 22:40:19

对不起 - 我误解了你的回答。删除downvote，谢谢澄清 – user2290362 2015-08-29 17:30:30

感谢您纠正。 – EliuX 2015-08-31 17:15:15
