[undertow-dev] exchange.dispatch() deprecation - safe to ignore?

Hello, I'm using the no-argument version of HttpServerExchange.dispatch(), and I just noticed that it's deprecated. I'm using dispatch() to suspend the exchange, to make sure the exchange isn't completed when the call stack returns. Basically I'm telling it, "Go to sleep. I'll be back later to finish things." Is that an inappropriate use of dispatch()? It's not clear that the suggested alternative of dispatch(Executor,Runnable) is better in this case. What arguments would I provide? dispatch(null, () -> {}) ? -Michael
