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

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

      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:
