Problem Vaadin 8.0.x / Eclipse / Jetty and @Push

From debug:

Client engine version8.1.5
Server engine version8.1.5
Theme version8.1.5
Push server version2.4.11.vaadin2
Push client version2.3.2.vaadin1-javascript (note: does not need to match server version)
Widget setAppWidgetset
Themetests-valo-dark
Communication methodClient to server: XHR, server to client: long-polling
Heartbeat300s

How to view all log-levels from Atmosphere and Vaadin?
I can view only SEVERE and WARNING
How to set FINER by default.
Note: main project code use LOGBACK

I get logs from Vaadin’s and Atmosphere’s JUL:
