> Manually setting service.isUp is overwritten by enricher (causing
> non-deterministic test failures)
> --------------------------------------------------------------------------------------------------
>
> Key: BROOKLYN-291
> URL: https://issues.apache.org/jira/browse/BROOKLYN-291
> Project: Brooklyn
> Issue Type: Bug
> Affects Versions: 0.9.0
> Reporter: Aled Sage
>
> If one creates an entity and explicitly sets its service.isUp to true, then
> the default enrichers can override this value to remove it. This is because
> it is executing concurrently, and if service-up-indicators is null then it
> removes the service.isUp sensor value!
> A similar thing happens for the service.state sensor.
> This is non-deterministic, but can be demonstrate with this simple test:
> {noformat}
> for (int i = 0; i < 100; i++) {
> TestEntity entity = app.addChild(EntitySpec.create(TestEntity.class));
> entity.sensors().set(TestEntity.SERVICE_UP, true);
> entity.sensors().set(TestEntity.SERVICE_STATE_ACTUAL, Lifecycle.RUNNING);
> Thread.sleep(10);
> assertEquals(entity.sensors().get(TestEntity.SERVICE_UP), Boolean.TRUE);
> assertEquals(entity.sensors().get(TestEntity.SERVICE_STATE_ACTUAL),
> Lifecycle.RUNNING);
> }
> {noformat}
> Most entities don't explicitly set the service.isUp, so it has not been a
> problem in production systems. However, it does impact tests - it is the
> likely cause of many non-deterministic test failures.
