      To reproduce, just start a server with a custom `Feature` which calls `ResteasyProviderFactory.getContextData(Dispatcher.class)` and you will notice it will be `null`.

    Description

      While working on https://github.com/resteasy/Resteasy/pull/1572 I noticed that the thread running `SseEventSourceImpl` has no thread context set-up for `ResteasyProviderFactory` and will use a singleton instead, which means it has no `Dispatcher` and all other required objects:

          Bug - A problem that impairs or prevents the functions of the product. RESTEASY-1916 InboundSseEvent.readData doesn't appear to use registered providers

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
