ReactiveWebApplicationContext swallows container startup exception #9221
Description
Consider the following project:
https://github.com/snicoll-scratches/test-spring-data-java9
Switch to Java9 and start it up (for instance via mvn spring-boot:run). You get something along the lines of:
