执行行 PDDocument.load(input)

时出现错误

代码示例：

PDDocument pd

String pdfDir = "C:/Users/user/Desktop/file.pdf"
File input = new File("${pdfDir}")

pd = PDDocument.load(input)  // System can't execute this line

pdfUtil.writePDF(pd, addr, data)

错误：

如评论中所述：文件为空。这通常是出现这样的异常的原因

IOException: Error: End-of-File, expected line

在堆栈跟踪中有 parseHeader。
