I use mule esb 3.7.0.
I have application A which sends an http request to mule esb, which forwards it to application B. The application B sends response back to mule esb, and mule esb sends it back to the application A. Everything works fine.
Then at one day the application B sends http response with a cookie (JSESSIONID, but it does not matter), and the application A throws timeout exceptions. I debugged mule esb and found this.
org.mule.transport.http.transformers.MuleMessageToHttpResponse->
protected HttpResponse createResponse(Object src, String encoding, MuleMessage msg) throws IOException, TransformerException

A similar question (not a duplicate because I have a different version of mule) NoSuchMethodError in Tomcat embedded MULE when executing http:set-cookie
Also I read this https://www.mulesoft.org/jira/browse/MULE-6705
It turns out, the problem is with libraries. We use Spring Boot, which has dependencies, and one of them overrides version of coyote.
provided group: 'org.apache.tomcat', name: 'coyote', version: '6.0.44'
With SpringBoot, it uses embedded-tomcat-core.
compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-core', version: '8.0.28'
