Hi,

Reactive feign is not yet compatible with spring 3.2, but it will come soon so please wait a bit ^^

Feign client is not added by default anymore. It may need to add feignClient true to jdl or use jhipster --feign-client for new applications. Upgrades will add it automatically.
Unfortunately there is nothing we can do with upstream bugs so I am closing.
