If you don't deal with UI stuff, this will not affect you.
It seems that bower > 1.7.2 have moved the bower's executable to another

for BTM. Hawkular is *not* affected, as long as it keeps using 1.7.2 (as
it's the case so far).
So, before updating Bower to a version higher than 1.7.2, make sure that
the following bug on frontend-maven-plugin is fixed:
