Delivering static resources with wrong contenttype since 4.3RC1 (not in latest 4.2 release) [SPR-14196]

[spring-projects-issues]

Jens Goldhammer opened SPR-14196 and commented

I am running a spring boot application and just made an upgrade to Spring Boot from 1.3.3 to 1.4M2.
I have packaged my application as war file and also deliver static resources within my app to browsers, especially markdown files.

In Spring 4.2, markdown files were responded with correct content type.
In Spring 4.3RC1, markdown files are delivered back with json contenttype which leads to an error in the browser which tries to parse it as json and fails.

See conversation here:

Any idea where I can debug or what is missing here? Are there any changes in Spring MVC?

This could be related to the changes for #18233. Can you provide steps or sample code to reproduce the issue?

Jens Goldhammer, suggestions?

This looks like a potential duplicate #19146. Jens Goldhammer can you confirm if that's the case, in particular I would expect that that you also have favorPathExtension=false.
