+/**
+ * TimerReuseTestCase verifies that it is safe to add a callback BisocketClientInvoker
+ * after the static Timer used by the PingTimerTasks has shut down because all previous
+ * PingTimerTasks have ended.
+ *
+ * See JBREM-748.
+ *
+ * The phenomenon described in JBREM-748 seems to be platform dependent. It's not clear,
+ * for example, how long it takes for a Timer to shut down after all of its tasks have
+ * ended. Therefore, there are multiple test methods that wait varying amounts of
+ * time before installing a second InvokerCallbackHandler.
