|
|---|

|
|---|
| 37 | <para>See the introduction to the Java language and system at
|
|---|
| 38 | <xref linkend="java"/>. The GNU Compiler Collection (GCC) contains
|
|---|
| 39 | a Java compiler to native code. Together with the
|
|---|
| 40 | <application>ecj</application> Java compiler from Eclipse (to bytecode),
|
|---|
| 41 | it provides a way to build an acceptable JVM from source. However, since
|
|---|
| 42 | the release of <application>OpenJDK</application>, the development
|
|---|
| 43 | of GCC-Java has almost stopped, and the built JVM is an old version.
|
|---|
| 44 | One reason to build
|
|---|
| 45 | this system is that it can be used to bootstrap <xref linkend="openjdk"/>,
|
|---|
| 46 | without the need for downloading a Java binary.</para>
