Q:

Official spring-boot SSL examples failing

I'm finding that the SSL examples provided in the spring-boot project are not working for me. 
For this example: 
https://github.com/spring-projects/spring-boot/tree/1.5.x/spring-boot-samples/spring-boot-sample-tomcat-ssl/src/main/java/sample/tomcat/ssl
And this example: 
https://github.com/spring-projects/spring-boot/tree/1.5.x/spring-boot-samples/spring-boot-sample-tomcat-multi-connectors
Instead of getting 'hello world', I get 

The startup log does not seem to show any issues.
Do these sample projects work for others? 

A:

For me, it works well. Here is what I did:
Clone the Spring Boot repository:
git clone https://github.com/spring-projects/spring-boot

Checkout the 1.5.7 branch
git checkout v1.5.7.RELEASE

Build
mvn package

Run
java -jar target/spring-boot-sample-tomcat-ssl-1.5.7.RELEASE.jar

Then open a browser on https://localhost:8443, accept the self-signed certificate and read the hello word message.
P.S.: I'm using Oracle JDK 1.8.0_144 and maven 3.5.0
