We have a lot of third-party jars (less than 100 probably) and did a bit
of work to make this work better for building, for managing version
conflicts and making life easier for developers.

Hey guys.
I think there’s a bug with Maven 3.2.5 and threaded builds and dependencies.
We have a LOT of dependencies. I think 400 or so external .jars (not sure
if we’re an unusual case or not).
Anyway. If we have an empty cache, and do a threaded build, what happens is
there’s a race around downloading a dependency.
Thread A will try to download foo.jar and so will thread B…
There’s no mutual exclusion locking present
This means we see the following issue:
- zero byte .jars with no data (not sure how that ones possible but we see
it).
- file not found when trying to copy the .part to the final .jar because
another thread has done so already.
I haven’t tested 3.3.3 because we’re in a CI environment and I can’t
upgrade maven easily.
This will be hard to write a test for I think.
