Steve, Thank you for that important addition.
Is it true that this, also, is not a special case? In other words, is this how it works? - the input queue contains both Events and Runnables (from runLater() and the first one containing a call to Application.start()) - one item is processed from the input queue at a time - if the processing of that item does a Dialog.showAndWait(), then: - - the processing of that item is suspended (the thread blocks?) until showAndWait() returns and - - a new item processor picks the next item off of the input queue & starts processing it It looks like the "JavaFX Application Thread" is the item processor.

In that case, your runnable will run. You are correct about runnables and input events being part of the input queue for the application thread. Threads are not interrupted to run code.
