Connections don't seem to re-connect

See original GitHub issue

When testing Hono I ran into the following scenario, the message flow works fine until the internal token expires. This will cause the connection to the adapter be terminated. The service should re-connect automatically but this doesn’t seem to work. Instead I do see the following messages in the log file:

The location which seems to map is in org.eclipse.hono.adapter.http.AbstractVertxBasedHttpProtocolAdapter.doUploadMessage(RoutingContext, String, String, Buffer, String, Future<MessageSender>, String) on line 494. A message of null most often indicates a null pointer exception.

So calling disconnect() and then isDisconnected() should still return false, as the transport still is non-null.

This looks like a bug in ProtonConnectionImpl. doesn’t it? Shouldn’t the disconnect method also set transport to null like fireDisconnect does?

I think so. From a Hono perspective we have a solution.
