The TCK test passes despite the logged error,

The test code schedules a repeating task and cancels it,

    public void testApiScheduleWithFixedDelay() {
        ScheduledFuture<?> result = null;
        try {
            EJBJNDIProvider nameProvider = ServiceLoader.load(EJBJNDIProvider.class).findFirst().orElseThrow();
            result = scheduledExecutor.scheduleWithFixedDelay(
                    new CounterRunnableTask(nameProvider.getEJBJNDIName(), TestConstants.pollInterval), // task
                    TestConstants.pollInterval.getSeconds(), // initial delay
                    TestConstants.pollInterval.getSeconds(), // delay
                    TimeUnit.SECONDS); // Time units
            Wait.sleep(TestConstants.waitTimeout);
            Assertions.assertBetween(counter.getCount(), (TestConstants.pollsPerTimeout / 2) - 2,
                    (TestConstants.pollsPerTimeout / 2) + 2);
        } catch (Exception e) {
            fail(e.getMessage());
        } finally {
            if (result != null) {
                Wait.waitCancelFuture(result);
            }
            counter.reset();
        }
    }

If the task happens to be running and is in the middle of its sleep operation when cancelled, the sleep operation will be interrupted, in which case the CounterRunnableTask chooses to raise a RuntimeException chaining the InterrruptedException, which Liberty rightly logs a message for.

    public void run() {
        try {
            if (!sleepTime.isZero()) {
                Wait.sleep(sleepTime);
            }

            CounterInterface counter = InitialContext.doLookup(countSingletionJndi);
            counter.inc();

        } catch (Exception e) {
            throw new RuntimeException(e);
        }

    }

If the test case is going to do this, then it needs to tolerate the warning in the logs.
