Great, thank you very much! As I really like to switch back to the master releases, do you know when you will create a new release?

[sbraconnier]

It will be within the next 2 weeks.

                .hostName("192.168.86.128")
                .taskExecutionTimeout(5 * 60 * 1000L)
                .taskQueueTimeout(1000 * 1000 * 60 * 24L)
