-------------------------------
Hi Ben, unfortunately I got my simple app (as explained at PLC4J getting
started) not working with 0.9.0. In 0.8.0 all works fine but in 0.9.0 I got an
exception while connecting to "opcua:tcp://localhost:12686/milo"

because sessionResponse.getServerEndpoints() is empty and policyId is still
null at line 494.
Switching discovery on/off has no affect.
Is it possible to use an "unsecure" channel?
