Hi community, I can not get the servlet option 'attachmentMultipartBinding=true' to work in combination with the Undertow embedded server in Spring Boot.
When sending HTTP multipart/form-data requests to a Servlet endpoint configured with the option attachmentMultipartBinding=true, the different parts of the request should be bound the Camel Exchange as attachments. This does not work when running the route in Spring Boot with the Undertow embedded server. When using Tomcat/Jetty it does work. I have created a simple route that logs the number of attachments to demo the problem: https://github.com/souheilallaoui/camel-file-upload. Am I missing something here or is it a bug? I am using Spring Boot 2.7.5 with Camel 3.18.3 Regards, Souheil
