I am creating a spring batch application using spring boot and mysql as the JPA repository and deploying on cloud foundry. While duing cf-push the batch process is crashed with error Process crashed with type web. However the underlying error message shows

回答1:
I think I have an autowired JobLauncher and @Bean JobLauncher which made two calls to DB at the same time(atleast I am thinking this as the reason :) ). When I removed the @Bean JobLauncher as I am using Spring boot, the application started working fine.
