Hi @spencergibb I created a minimal repo with my setup here boot 3.2.2 and cloud 2023.0.0 here [gateway](https://github.com/bsgrd/gateway) I'm gonna test with your initializer setup.

@spencergibb weird. I'm doing a simple POST request with postman and a random json body. I also just tried a curl request with same result: `curl -H 'Content-Type: application/json' -d...

BTW. I should mention that I'm using Java 21. Don't know if that makes a difference. Though i get the same error with java 17.

@spencergibb I'm still getting the same error with your fix. I have added a screenshot and the stacktrace.  [stacktrace.txt](https://github.com/spring-cloud/spring-cloud-gateway/files/14584157/stacktrace.txt)

@spencergibb I created my first PR here: https://github.com/spring-projects/spring-framework/pull/32432
