Consolidation of the JDK forest into a single repository

Prior to Java 10, there were eight repositories for the JDK (CORBA, HotSpot, JDK, JAXP, JAX-WS, langtools, Nashorn, and ROOT). With Java 10, these repositories have been consolidated into a single code base. Notably, Java FX was not part of this consolidation. This topic will be explained further in Chapter 2, Discovering Java 11.
