However, the return value of `doLockDiskStore()` is non-deterministic. I can't assert the return value of individual thread. I can only count and assert the number of returning values when all threads are done. I am not sure how `ExecutorServiceRule` will serve this test case. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
