title: Spring Boot 2.0.0.M1: Where is the package org.springframework.boot.context.embed?
body: <p>Spring Boot 1.5.3.RELEASE had several classes in <code>org.springframework.boot.context.embed</code> and also the subpackages <code>jetty</code>, <code>tomcat</code>, and <code>undertow</code>. However, <code>https://github.com/spring-projects/spring-boot/tree/v2.0.0.M1/spring-boot/src/main/java/org/springframework/boot/context</code> doesn't contain the subdirectory <code>embed</code> anymore.</p>
  
  <p>Where are classes like <code>TomcatEmbeddedServletContainerFactory</code> gone?</p>
