If you remove the concurrent.jar from lib/portal, different versions of it is copied if you have the liferay-binaries-cache-2017 repo cloned or if you don't.

Steps to reproduce:

1. Check out master (or 7.1.x or 7.0.x)
2. Run git -fdX to remove the files (or just delete the concurrent.jar)
3. Rename the ../liferay-binaries-cache-2017 folder
4. Run ant all

With these steps the size of the jar is 189284 - on all versions. Rerun the previous commands, but have the liferay-binaries-cache-2017 available. The size of the concurrent.jar will be 224078.
