Spring Cloud: observability vs. task execution listener

This sample project demonstrates an incompatibility with task observability and task execution listener implementations - either by implementing the TaskExecutionListener interface or using methods annotated with @BeforeTask, @AfterTask or @FailedTask.

If your task execution listener implements the ApplicationRunner interface and task observability is enabled, ObservationApplicationRunnerBeanPostProcessor wraps the task execution listener and the listener methods are no longer invoked.

Please refer to:

• FooTaskRunner: An implementation of the ApplicationRunner interface that also uses methods annotated with @BeforeTask and @AfterTask
• TaskListenerExecutorBugTest: A unit test that demonstrates the current and expected behaviour
