This changeset optimizes the Guava build significantly by enabling parallel build and test features supported by Maven. With these flags enabled, only a few tests exhibit flaky behavior; applying a sensible count of test retries (3) solves the problem. As a result, the testsuite can now be executed often, because it takes about 2 minutes to run. Building is also much faster. After benchmarking different configurations, 2-threads-per-core and 2-test-forks-per-core seems optimal: ``` [INFO] Guava Maven Parent .....................
