Start by running the unchecked tests listed in the issue, including AMQ4083Test, NetworkAdvancedStatisticsTest, and NetworkBridgeReconnectOnHandshakeFailureTest, to reproduce the failures. Read each test and its supporting test class to determine whether the failure is intermittent or a real regression. Done means the listed flaky failures are stabilized or fixed and the corresponding checklist entries can be marked complete.
