The key here is:
  http://www.apache.org/legal/3party.html#principles

By including GPL'd software into the distribution you are imposing
*more* constraints on (downstream) users. That is not allowed. End of
story. We want our end users to have as much flexibility as possible.
Our entire Foundation is constructed around our permissive ALv2
license. We *strive* to produce all of our products under that
license, or a similarly permissive approach. We hope that all of our
communities work to produce products under these
open/unconstrained/permissive licenses. Shoot for ALv2, and avoid the
reciprocal licenses where possible, so that we don't surprise our
downstream/users with surprising constraints.

You may include other software which is similarly permissive as the
ALv2. You may include user-choice dependencies of other other
licenses, which are optional (not mandatory/required). Don't surprise
our users. Permissive is the goal.

Cheers,
-g
