KopiSusu is a Java compiler based on the KOPI suite. KopiSusu improves on the 1.4F version of KOPI by following The Java Language Specification, Second Edition more closely. It also generates classfiles that are more compatible with the classfiles generated by Javac and Jikes in the area of inner classes.

The classfile format is described in Java Virtual Machine Specification, Second Edition.

Like the original KOPI, KopiSusu is licensed under the GNU General Public License.

KopiSusu has been tested with Jacks ("Jacks is an Automated Compiler Killing Suite") and does really nicely on it. Jacks contains more than 1600 tests, most of them for specific parts of the Java Language Specification. At the moment, KopiSusu has the least number of failures on the jacks test, compared with any Java compiler that I know of.

Check out the result of running jacks with Sun JDK1.3 and the lastest KopiSusu.

Other tests passed:

• Compiling and running itself.
• Compiling the GNU Classpath libraries (cvs version of 2nd half of march).
• Compiling kaffe 1.0.6 release. Some patches to kaffe are needed because kaffe contains some minor errors in the source that are not caught by most other compilers. Specifically, the JLS requires access to final fields in classes to be of the form "TypeName.Identifier" if they are used as constant expressions, such as in case labels inside switch statements. The necessary patch can be found on the Patches page.
• Compiling GNU Servlet API implementation.
• Compiling JBinHex.
• Compiling and running Antlr 2.7.1.
