Reference project for SCF Issue 623
See spring-cloud/spring-cloud-function#623 for the actual issue.
To run the application, run mvn package at the root of the application.
Within the example directory, run mvn spring-boot:run to start the server, which will listen on port 8080.
To trigger the issue in question, you can (un)comment one of the @Component annotations found within the function package in the example module.
With only one Function available, SCF will continuously throw an exception, preventing the application from running properly.
With two Functions available (by the usage of the @Component annotation), the application works normally.
