Build failure for camel-jetty, which displays bigger problems with content-type
handling for multipart forms
------------------------------------------------------------------------------------------------------------
Key: CAMEL-4094
URL: https://issues.apache.org/jira/browse/CAMEL-4094
Project: Camel
Issue Type: Test
Components: camel-http, camel-jetty
Affects Versions: 2.7.2
Environment: OpenJDK displays the problem, but actually there is an
issue with all platforms.
Reporter: Yaytay
Priority: Minor
Camel-jetty has a build failure in MultiPartFormTest when built with OpenJDK.
The assertion
assertEquals("Get a wrong content type", "text/plain", data.getContentType());
within the route causes a 500 error to be seen by the client (there is no
logging to the display of the assertion failure).
Further investigation has shown that:
1. The content-type sent with the HTTP request (for the file part) is always
"application/octet-stream", the default for FilePart - this does not appear to
be what is desired (the CamelFilePart class would fix it, but this doesn't seem
to be used).
2. The content-type for file parts is not made available by jetty, so
data.getContentType() always returns the default content-type for the
DataHandler class.
3. Different DataHandler implementations have different default content-types
(Sun has "text/plain", OpenJDK has "application/octet-stream").
It is the last difference that causes the build break, but that should be
irrelevant if the other two things were fixed.
I have raised [https://bugs.eclipse.org/bugs/show_bug.cgi?id=349110] against
jetty to try to get the content type made available, but until that happens
I've got a patch to simply remove the incorrect assertion.
