I am using Wiremock (which appears to use jetty) to stub some http responses.
I am sending a multipart http request but Wiremock/jetty responds to with a 500 error and some html which details a MalformedStreamException.
This has only broken since a version upgrade of Wiremock from 2.31.0 to 2.32.0.
I am sending the following request in Postman to my stub endpoint:
Headers
Content-Type: multipart/related; boundary=xxx
Request body
--xxx
Content-Type: text/xml; charset=UTF-8
<?xml version="1.0" encoding="utf-8"?>
<test></test>
--xxx
Content-Type: text/xml; charset=UTF-8
<?xml version="1.0" encoding="utf-8"?>
<test></test>
--xxx--

Can anyone spot anything I am doing wrong or have any suggestions of things to rule out or try?
Could there be a bug in Wiremock or one of its dependences or is my multipart request malformed?
Update I've opened a bug on Github: https://github.com/wiremock/wiremock/issues/1973
