Java ImageIO.read让一些东西挂起......

Question

我将图像的byte []转换为具有已定义宽度和高度的jpg，并将该图像存储在我的amazon s3上，但是我刚刚发现java上的某些内容正在“挂起”＃39;就在我使用ImageIO.read指令的行之后。我只注意到它，因为在调用ImageIO.read行时java控制台会打开，但在关闭我的应用程序之前永远不会关闭。我已经检查过关闭我在代码中找到的所有缓冲区和流，但即使图像保存在亚马逊上，控制台仍会打开。有没有办法检查发生了什么？我一直在阅读stackoverflow，ImageIO.read有一些内存泄漏问题。

这是我的代码：

private byte[]  transformImageToJpg(byte[] receivedImage, int width, int height) {
    if (receivedImage == null)
        return null;

    InputStream is = null;
    BufferedImage bufferedImage = null;
    byte[] imageInByte = null;
    try {
         is = new ByteArrayInputStream(receivedImage);
        bufferedImage = ImageIO.read(is);
        if(bufferedImage == null) {
            receivedImage = null;
            is.close();
            showError("Invalid File", "The selected file is not a valid image file.");
            return null;
        }

        int w = bufferedImage.getWidth();
        int h = bufferedImage.getHeight();
        BufferedImage newBufferedImage = new BufferedImage(width,
                height, BufferedImage.TYPE_INT_RGB);
        newBufferedImage.createGraphics().drawImage(bufferedImage, 0, 0, width, height, 0, 0, w, h, Color.WHITE, null);

        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        ImageIO.write(newBufferedImage, "jpg", baos);
        baos.flush();
        imageInByte = baos.toByteArray();
        newBufferedImage.flush();
        bufferedImage.flush();
        baos.close();
        is.close();
        receivedImage = null;
    } catch (IOException e) {
        e.printStackTrace();
    }
    return imageInByte;
}
