Is it possible to schedule a task on the Websocket delivery thread?

I am using the Whole Message Delivery functionality of Jetty Websockets. In such a case, Joakime says that Websocket messages are guaranteed to be delivered in order.

I am going to go on a limb and assume that all Websocket event-handling methods will be invoked by the same thread.

Now, say an external timer expires and I need to send a message over the websocket. The timer runs in one thread and the Websocket events run on a different thread.

Do I need to make my Websocket event handlers thread-safe (seeing as their state will be accessed by the timer and Websocket thread)? Or is there a way for the timer thread to pass a task to the Websocket thread to execute?

The Jetty WebSocket API (Native or javax.websocket) doesn't care about the thread safeness of the local WebSocket End Point.

It will deliver the next message when it arrives.

Note: you can control suspend / resume of the read thread with the Jetty Native WebSocket API.
