GNU Classpath (essential libraries for Java) is a project to create free core class libraries for use with virtual machines and compilers for the Java programming language. It includes all native methods and core classes necessary for a completely functional execution environment.

Changes:
The main feature of this release is major changes to Classpath's build system. Notably, configure now tries to find ecj, javac, and gcj (in that order), and the --with-ecj and --with-javac options were removed. To override this, set JAVAC when calling configure. Building also now requires a version of javah so that headers may be generated. There have also been many bugfixes over the past four months.
