| 38 | See the introduction to the Java language and system at
|

| 39 | <xref linkend="java"/>. The GNU Compiler Collection (GCC) contains
|

| 40 | a Java compiler to native code. Together with the
|
|---|
| 41 | <application>ecj</application> Java compiler from Eclipse (to bytecode),
|
|---|
| 42 | it provides a way to build an acceptable JVM from source. However, since
|
|---|
| 43 | the release of <application>OpenJDK</application>, the development
|
|---|
| 44 | of GCC-Java has almost stopped, and the built JVM is an old version,
|
|---|
| 45 | which cannot be used for building <xref linkend="openjdk"/>.
