----------------------------------------
Summary: Websocket exception using async remote
Key: WFLY-4480
URL: https://issues.jboss.org/browse/WFLY-4480
Project: WildFly
Issue Type: Bug
Components: Web Sockets
Affects Versions: 9.0.0.Beta2
Reporter: nicolas desmaziers
Assignee: Stuart Douglas
Sending binary messages on the AsyncRemote endpoint throws an error in the log:
21:11:28,747 ERROR [org.xnio.listener] (default I/O-6) XNIO001007: A channel event
listener threw an exception: java.lang.IllegalStateException: XNIO000017: Buffer was
already freed

This happens after a few minutes and generally the number of errors increase rapidly and
we can easily have a 2Go log after a few hours.
Code is:
session.getAsyncRemote.sendBinary(event.asReadOnlyBuffer(), new SendHandler(){
override def onResult(result:SendResult) {
}
})
It worked well with wildly 9.0 alpha 1 but bug appeared with beta 2.
I generally receive a close event on the web socket session after the error logging.
