ScheduledAnnotationBeanPostProcessor registers schedules twice in web application [SPR-6656] #11322
Description
Christian Ihle opened SPR-6656 and commented
ScheduledAnnotationBeanPostProcessor.onApplicationEvent is first run when the Root WebApplicationContext initializes. Then run again when the FrameworkServlet initializes. Each time onApplicationEvent runs a new schedule is registered.
I have modified the task-basic sample from https://src.springframework.org/svn/spring-samples/task-basic/trunk/ to run as a web application for verification. Will attach the source and war file.
This is the console output of task-basic in jetty. It's the same in tomcat. Notice the "processing next 10..." text that shows up twice every 30 seconds. When the application runs from a main class outside a web server the "processing next 10..." text only shows up once every 30 seconds.
