[magnolia-dev] Custom Widgetset for Mgnl 5.5

AFAIK Magnolia 5=2E5 still relies on Vaadin 7=2E7=2C which again depends on=
 a GWT version that doesn=27t support Java 8 language level=2E

On the other hand it looks like even the widgetsets of Magnolia 5=2E5=2Ex h=
abe lambda expressions=2C e=2Eg=2E

            =7D

This is out from magnolia-ui-vaadin-common-widgets-=5Bb=5D5=2E5=2E6=5B/b=5D=
=2E

This gives me errors like

How can I create custom widgetsets for Mgnl 5=2E5=2Ex=3F

Thx
