java - Java try-catch-finally 中的奇怪错误

Question

我正在使用 JODConverter 将 .xls 和 .ppt 转换为 .pdf 格式。为此，我有类似的代码

try{
    //do something
    System.out.println("connecting to open office");
    OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);
    System.out.println("connection object created");
    connection.connect();
    System.out.println("connection to open office successful");
    //do something
    if(!successful)
      throw new FileNotFoundException();
}catch(Exception e){
   System.out.println("hello here");
   System.out.println("Caught Exception while converting to PDF ");
   LOGGER.error("Error in converting media" + e.getMessage());
   throw new MediaConversionFailedException();
}finally{
   decode_pdf.closePdfFile();
   System.out.println("coming in finally");
  //do something here
}

我的输出:

connecting to open office
connection object created
coming in finally

附言方法的返回类型为 void

这怎么可能？即使 connection.connect() 中有问题，它也会出现在 catch block 中。 困惑

Answer 1

可能抛出了一个错误。这仍然会导致 try block 未完成，忽略 catch 异常 block 并调用 finally block 。
