The test classes exercised by Geode's acceptanceTest, distributedTest, integrationTest, performanceTest, uiTest, and upgradeTest tasks typically do not leave the test worker JVM in a state where other test classes can succeed. For this reason, these tasks all specify `forkEvery = 1`, giving each test class a fresh test worker JVM.
The corresponding repeat test tasks leave `forkEvery` at the default value, which runs multiple test classes in each test worker. This produces swarms of test failures. For example, running all distributed tests via `repeatDistributedTest` produces about 1450 test failures.
Repeat test tasks should specify `forkEvery = 1` to run each test class in a fresh test worker JVM.
