Thanks for the report. This will have to be addressed in Lettuce (cc @mp911de) and Reactor (cc @simonbasle). We'll pick up any resulting Lettuce or Reactor releases in due course.

yes, Lettuce 6.1.x apparently depends on reactor-core 3.3.x (which is EoL) and causes this issue. From what I can see, in the current main @mp911de is working towards a Lettuce 6.2.x which depends on reactor-core 3.4.x for now, which should eliminate this particular problem. I wonder if there's a plan to support reactor-core 3.5 directly instead, but the two lines should be compatible.

Comment From: mp911de

For the time being, please configure ClientResources.eventBus with an empty bus emitter if you don't actively consume Lettuce client events.

As Simon mentioned, Lettuce 6.2 is in the making and we cannot upgrade to Reactor 3.4 or 3.5 in a Lettuce 6.1.x minor release.

@mp911de The error reported here doesn't appear to be related to the EventBus. I only see a problem with EventBus and its use of DirectProcessor when upgrading Reactor from 2022.0.0-M2.

Comment From: mp911de

I missed that detail. I fixed recently the Processor deprecation in Lettuce and missed the subscriberContext problem because it was fixed already in the main line. Lettuce 6.2 is in progress and I expect a release early next week.
