Summary

0003766: file servlet throws ArrayIndexOutOfBoundsException with negative range

Description

reported by Knut Forkalsrud
  Accept-Language: zh-cn,zh-hk,zh-tw,en-us
          User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
          Accept: */*
          Host: www.mydomain.com
          Connection: Keep-Alive
          Range: bytes=-335544320--1162852624
          Accept-Encoding: gzip
          X-Forwarded-For: 124.115.0.146

This results in an exception like this:

(I'm forwarding the request to the FileServlet). No harm done here, the requests seems to fail
without causing any other side effects, but I'm wondering if the FileServlet should handle the
situation a little more gracefully and give a 4xx response code instead of throwing an exception,
which ends up being a 5xx response code.
