疑难解答：JDialog 是模态的，但不是模态的？

对此感到困惑，但也许，只是也许，有人以前遇到过这个问题，可以为我指明正确的方向。

我有一个 JDialog 用于显示长时间运行的任务的进度，我已将其明确创建为具有定义的所有者的模式：

  progressDialog = new JDialog( ((Dialog)windowParent), true );
  ...
  progressDialog.setVisible( true );

稍后，一旦任务完成，我会再次关闭对话框：

protected void done() {
  SwingUtilities.invokeLater( new Runnable() {
     public void run() {
        progressDialog.setVisible( false );
     }
  } );
}

在非常罕见的情况下，对话框) 不会关闭，并且 b) 不是真正的模式，即用户能够与（理论）对话框后面的窗口进行交互。有什么想法可能导致这种情况吗？不幸的是，这种情况很少发生，而且到目前为止，仅在 Linux 系统上发生。这可能是 Swing 错误还是我可能做错了什么？

Stumped by this, but maybe, just maybe, someone has had this problem before and can point me in the right direction.

I have a JDialog for displaying the progress of a long-running task, which I have expressly created as modal with a defined owner:

  progressDialog = new JDialog( ((Dialog)windowParent), true );
  ...
  progressDialog.setVisible( true );

Later on, once the task is complete, I close the dialog again:

protected void done() {
  SwingUtilities.invokeLater( new Runnable() {
     public void run() {
        progressDialog.setVisible( false );
     }
  } );
}

Under very rare circumstances, the dialog a) does not close, and b) is not truly modal, i.e. the user is able to interact with the window behind the (theoretical) dialog. Any ideas what might be causing this? Unfortunately it happens very rarely and until now, only on Linux systems. Could this be a Swing bug or am I possibly doing something wrong?
