Spring-boot: Spring boot application (1.4.0) fails to start due error with printing banner

[interair]

There is issue with printing banner at headless jvm: but from my point of view such issue shouldn't prevent starting whole application:
Environment:

FROM debian:stretch
RUN apt-get update && apt-get install -y --no-install-recommends openjdk-8-jdk-headless && apt-get clean
ADD ./spring-boot.jar /spring-boot.jar
ENTRYPOINT java -server -jar spring-boot.jar

Spring boot: 1.4.0.RELEASE

Exception:

ERROR o.s.b.SpringApplication - Application startup failed

We probably can't display the banner without AWT support, but I agree that we should still let the app run.

BTW, deleting banner.gif will bypass that code in the meantime.

Or you can disable the banner via configuration spring.main.banner-mode=off

Thank you
spring.main.banner-mode=off
works
