Warning when launching with Java11

[klag]

If I am running the client server example with java 11, the following warning appears:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.eclipse.paho.client.mqttv3.internal.FileLock (file:/home/...bla bla bla.../lib/org.eclipse.paho.client.mqttv3-1.1.2-20170804.042534-34.jar) to method sun.nio.ch.FileLockImpl.release()

I am running a local broker inside a docker container: https://hub.docker.com/_/eclipse-mosquitto version 1.6.14.
I am using port 1883.

Hi Claudio.
Unfortunately, these warnings are due to the Paho library and there seems to be no way to avoid them (eclipse-paho/paho.mqtt.java#794).

Apart from the warnings, is the service working? Can you send and receive messages?

Hi Riccardo, yes it is working so no problem for now!
I would leave the issue opened, until paho library release a fix. What do you think?

[rickyiatto]

Yes, I agree with you.
