Start with SeatunnelApplication.main and the Spring Boot web-server startup shown in the stack trace, then compare the provided seatunnel HTTP configuration with the seatunnel-web 1.0.2 runtime. Reproduce the failure using sh download_datasource.sh start and trace the Jetty "No selectors" error; done means the application starts its web server successfully with the reported Java 8 environment.
