parseRequest randomly throws Stream ended unexpectedly
------------------------------------------------------
Key: FILEUPLOAD-106
URL: http://issues.apache.org/jira/browse/FILEUPLOAD-106
Project: Commons FileUpload
Type: Bug
Versions: Nightly Builds
Environment: The client and server environments are all Solaris 9, Java
1.4.2_05, JBoss
3.2.5 running Tomcat 5.0.26 using the default 8080 connector, and separated by
a few LANs with very low latency (2ms).
Reporter: Gerald Turner
Hello, I have an application using FileUpload which intermittently encounters
this error as well, about once every 100 uploads. It's a simple servlet that
writes posted files to disk. The client application that is posting to this
FileUpload servlet is using Jakarta Commons HttpClient 3.0.1 with features such
as MultipartRequestEntity and MultiThreadedHttpConnectionManager.
Typically the posts contain two to three FileParts, a few 20KB audio/x-wav
files accompanied by a 15KB application/voicexml+xml file.
The servlet is actually running on two different servers, and the single client
posts to both of them, this occasional "Stream ended unexpectedly" error will
occur on one server and still succeed on the other.
The client and server environments are all Solaris 9, Java 1.4.2_05, JBoss
3.2.5 running Tomcat 5.0.26 using the default 8080 connector, and separated by
a few LANs with very low latency (2ms).
It's interesting to note that the FileUpload servlet catches the "Stream ended
unexpectedly" exception during parseRequest and is still able to
HttpServletResponse.send(500, e.getMessage()), which the client receives and
there are no other errors leading me to indicating the socket connection was
ganked.
I've applied a patch to the latest FileUpload 1.2-SNAPSHOT in SVN for including
the root cause in exceptions, e.g.:
+++ src/java/org/apache/commons/fileupload/FileUploadBase.java

} catch (IOException e) {
- throw new FileUploadException(

- + " request failed. " + e.getMessage());
+ throw (FileUploadException) new FileUploadException(
+ "Processing of " + MULTIPART_FORM_DATA
+ + " request failed. " + e.getMessage()).initCause(e);
}
Here is a stacktrace of one of the random "Stream ended unexpectedly"
exceptions:

The other server happily accepted the same upload:
