java.io.FileNotFoundException: Source '\tmp\upload__3a3bcc78_143699__8000_000014.tmp' does not exist

今天在做多文件上传的时候出现了这个异常，报错语句是

at org.apache.commons.io.FileUtils.copyFile(FileUtils.java:636)at org.apache.commons.io.FileUtils.copyFile(FileUtils.java:606)

从字面上看说是.tmp文件未找到，应该是服务器接收文件后，建立的缓存文件出了问题

最后发现是由于我上传的三个文件中有一个txt文件没有内容，只要有1个字符就不会再报这个异常，具体原因尚不明确，等待高手解决
