Nice catch, thank you for the contribution!
Just a nit: would it be possible to use AssertJ for more expressive assertions?
Other than that, the PR is fine.

Nice catch, checking for == was wrong because of the race condition (2 threads executing numShouldCancelCalled[0]++; before one of them reached the if below would skip numbers).
FTR it is now safe to simply do:
return numShouldCancelCalled.incrementAndGet() == NUM_JOBS_LIMIT;... because the comparison (==) uses the now stable value that comes from incrementAndGet() (no race condition there).

I'd rather be safe here with >=.
Adjusts JobGroupTest.testShouldCancel_4() to use an atomic data structure, to avoid concurrency issues with incrementing an integer from multiple jobs. See: eclipse-platform#2667
