Description

When calling send with CompletionListener, the api indicates this create an async call.

However, it seems that internally, there is still blocking.

JmsSession has this code:

transactionContext.send(connection, envelope, null)

This in turn, calls:

connection.send(envelope, new ProviderSynchronization() {

And in there:

try {
    provider.send(envelope, request);
    request.sync();
} finally {
    requests.remove(request);
}

the sync call is blocking. so it seems there is no real async implementation?

Also, the sync is called without timeout even if user sets a

sendTimeout
