This issue has revealed another problem: we still have deprecated
initialization methods taking an ExtendedProperties object. But I had
totally overlooked the fact that since we now use shading, the method
signatures will change anyway. Even if we avoid shading this one
specific class, we can't decently keep an undeclared dependency, even
for backward compatibility.
To upgrade, frameworks using this setExtendedProperties method just have
to use it with our cloned class, o.a.v.util.ExtProperties.
Plus, getting rid of ExtendedProperties can allow us to upgrade our
dependency to commons-collections v4.1.

The Velocity upgrading page states that •commons-lang,
commons-collections and commons-logging aren't needed any more at
runtime.
However, commons collections is still required. Here is the error
received when using the latese version (4.1) of commons-collections jar:
