使用 ajaxFileupload 异步上传文件，报错 org.eclipse.jetty.io.EofException: early EOF 

日志信息： 

java.lang.RuntimeException: org.eclipse.jetty.io.EofException: early EOF

at com.jfinal.upload.MultipartRequest.wrapMultipartRequest(MultipartRequest.java:123)

at com.jfinal.upload.MultipartRequest.<init>(MultipartRequest.java:68)

at com.jfinal.core.Controller.getFiles(Controller.java:767)

at com.jfinal.core.Controller.getFile(Controller.java:772)

at com.oss.project.ProjectController.ajaxUploaddemo1(ProjectController.java:166)

看了源码 是 com.oreilly.servlet 创建 报错 

multipartRequest = new  com.oreilly.servlet.MultipartRequest(request, uploadPath, maxPostSize, encoding, fileRenamePolicy);

不知大家是否遇到过，需要如何处理 ？
