Hmm. That's not going to work. Need the fix from reactor/reactor-core#1033

@mp911de Just a heads up that we actually need Californium. I've upgrade to M1 for now. Is this going to be a problem for you?

Works for us. Spring Data is following the most recent Reactor upgrades and it looks like as if the Reactor Netty upgrade is already in place. I was only concerned about the fact having Californium for Reactor Core but Bismuth for Reactor Netty.
