;; The Java bootstrap begins with Jikes, a Java compiler written in C++. We
|
||
;; use it to build a simple version of GNU Classpath, the Java standard
|
||
;; library. We chose version 0.93 because it is the last version that can be
|
||
;; built with Jikes. With Jikes and this version of GNU Classpath we can
|
||
;; build JamVM, a Java Virtual Machine. We build version 1.5.1 because it is
|
||
;; the last version of JamVM that works with a version of GNU classpath that
|
||
;; does not require ECJ. These three packages make up the bootstrap JDK.
|
||
|
||
;; This is sufficient to build an older version of Ant, which is needed to
|
||
;; build an older version of ECJ, an incremental Java compiler, both of which
|
||
;; are written in Java.
|
||
;;
|
||
;; ECJ is needed to build the latest release (0.99) and the development
|
||
;; version of GNU Classpath. The development version of GNU Classpath has
|
||
;; much more support for Java 1.6 than the latest release, but we need to
|
||
;; build 0.99 first to get a working version of javah. ECJ, the development
|
||
;; version of GNU Classpath, and the latest version of JamVM make up the
|
||
;; second stage JDK with which we can build the OpenJDK with the Icedtea 2.x
|
||
;; build framework. We then build the more recent JDK Icedtea 3.x, and all
|
||
;; other versions of OpenJDK.
