SpringBoot 2.0 VERY slow to start up on MacOS Sierra - spring-boot

Question

Has anyone experienced a very slow startup time for SpringBoot 2.0 on MacOS Sierra?
My pom is nothing more than this (snippet):
...
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.0.RELEASE</version>
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
...
It takes 22 seconds to start up:

Any ideas?
Ok, StackOverflow is making me add "more details". Not sure what else to add here.

Answer 1

Ok, figured it out. It had nothing to do with Spring Boot 2.0. Just happened to coincide with that upgrade.
The real answer is from this StackOverflow:
Maven with Surefire (TestNG) is slow after update to MacOS Sierra

Answer 2

Set it like this
open your terminal and run hostname
$ hostname
xxx.local
modify the host config in file /etc/hosts
127.0.0.1 localhost xxx.local
::1 localhost xxx.local
