Wildfly 8.2 : org.xnio.channels.FixedLengthUnderflowException: 8088 bytes remaining

Question

I am migrating from jboss 6 to jboss 8.2. Earlier it was working without any exception but now when I try to download a file , I get below exception

Caused by: org.xnio.channels.FixedLengthUnderflowException: 8088 bytes remaining

Code snippet

ContentType = "application/octet-stream";
BufInput = new BufferedInputStream(new FileInputStream(File), 5000);
Response.reset();
Response.setIntHeader("Expires", 0);
Response.setContentType(contentType);
Response.setHeader("Content-Disposition", header);
Response.setIntHeader("Content-length", (int) File.length());
Response.setContentLength((int)File.length());
OutStream = new BufferedOutputStream(Response.getOutputStream(), 5000);
int Byte;
while ((Byte = BufInput.read()) != -1)
    OutStream.write(Byte);
OutStream.flush();
OutStream.close();
BufInput.close();

This was fixed in 8.2.1 and 9.0.x

So solution for you is to upgrade.

After restarting the server (8.2.1), first time when I click to download file I get "General Error.General input/output error.". And if I click once again to download then It works fine. – happy Aug 17 '15 at 12:16
When I remove Response.setIntHeader("Content-length", (int) File.length()); Response.setContentLength((int)File.length()); It works fine both on 8.2.0 and 8.2.1 – happy Aug 17 '15 at 12:16
