Running my Spring boot project in Java 10 and maven everything ran fine. Simply changing the JDK from 10 to 11 introduced the following error

I am not using the Spring Webflux framework, and have not needed any jars with the reactor framework before. I know Java 11 gutted a lot of the JEE stuff out of the JDK, but this isn't that.
I have tried SpringBoot 2.0.5 release and the latest milestone release (M4) of 2.1 and the results are the same. I have changed the Spring Cloud version from Finchley.SR1 to Greenwich.M1 with the same results.
Has anyone else ran into a similar problem? Any help is greatly appreciated.
Edit: simply adding reactor core to my Pom as a managed dependency causes another issue of it not finding Netty libraries... which is weird because it should be using tomcat.
