Thank you for the contribution.

In the pom.xml line 53 seems to be code formatting issue, perhaps you used tabs instead of spaces.

@chrisnaan Thanks for quick action.

I am curious to know, are you using OSGi with Liferay or Karaf ?

We're using Liferay DXP 7.3, we have some legacy Vaadin 7 code we need to get working on Liferay 7.3

@TatuLund I don't think this is ready to merge yet, as there are dependencies this module uses that aren't osgi modules either.
