Hi Renier,

Unfortunately I think the current GWT compiler version does not support Java 8, so you can't use its features when writing client-side code :(

I know this is an old thread, but the issue still persists so maybe others could benefit from my findings.

Vaadin-client in version 7.7.6 depends on GWT 2.7 (2.7.0.vaadin4 actually) which does not support Java 8 but GWT 2.8 already does. Vaadin 8 will depend on GWT 2.8, but until it is released we can still tweak 7.7.6 to use GWT 2.8 on our own risk as written in this article.
