Swing文本组件无法从剪贴板粘贴大文本数据:java.io.IOException:所有者无法转换数据

我正在直接和通过JTextComponent接口使用JTextArea，试图将基于Swing的应用程序（记事本）外部的文本数据粘贴到应用程序中。

使用两种不同的方法（如下所示），对于大量的文本数据，我似乎得到了相同的结果。只要我坚持使用少量(<25K)，它就可以正常工作，但是粘贴在大约1.5MB的域白名单中似乎会导致IOException。我在网上看到了许多关于各种应用程序的文章，提到它是1.6 JVM中的一个bug。我目前正在使用JDK1.7.0_25，我想知道是否有人知道解决方案或变通方法？？？

我也有可能把这件事完全搞错了。。。

code:code/code>

@Override
public void actionPerformed(ActionEvent ae) {
    String cmd = ae.getActionCommand();     
    log.debug("Running {}",cmd);

    if (cmd.equals("copy")){
      this.component.copy();
    } else if (cmd.equals("paste")){

        // Simple paste -- but large data doesnt paste
        this.component.paste();

    } else {
        log.warn("No handler for {}", cmd);
    }
}

也尝试了:

Clipboard c = Toolkit.getDefaultToolkit().getSystemClipboard();
Transferable t = c.getContents(this);
if (t == null)
    return;
try {
    component.setText((String) t.getTransferData(DataFlavor.stringFlavor));
} catch (Exception e){
    e.printStackTrace();
}

异常:

额外的测试似乎表明这只发生在Linux操作系统上（我使用它来开发），但它似乎可以在windows上操作（我不使用它）。

我不知道它在大数据上是否会更好，但是您可以尝试使用DefaultEditorKit中的默认操作来进行复制:
JButton paste = new JButton( new DefaultEditorKit.PasteAction() );
该操作还可以添加到JMenuItem中。
