Apache Harmony 28 In the end of November, 2006, the language support provided by these virtual machine was still incomplete, and the build instructions recommended to use IBM's proprietary J9 instead to run the class library test suite. However, this is not necessary anymore (as of July 2007). The DRLVM virtual machine is currently (as of July 2006) under heavy development, so a fast improvement of its features can be expected. Applications status Since its conception, Harmony has steadily grown in its ability to execute non-trivial Java applications (see here [32] ). As of July 2007, supported applications include: • Eclipse : 99.3% of the 36000 RI test pass on Harmony's DRLVM + class library. [33]. • Apache Tomcat : 100% of the RI tests pass [34]. • JUnit : 100% of the RI tests pass [35]. • Apache Ant : 97% of the RI tests pass. [36]. • other applications pass with a high success rate, such as Apache Derby, Apache Axis, Log4j, Apache Velocity, Apache Cocoon, jEdit, and Apache Commons. However, Harmony's incomplete library prevents it from launching some other applications: • ArgoUML: because it requires a Java applet implementation, which is still not available in Harmony. • Apache Geronimo runs on Apache Harmony with some issues and workarounds [37] . • Vuze, formerly Azureus, because of unimplemented security classes.

development, so a fast improvement of its features can be expected.<br />

• ArgoUML: because it requires a Java applet implementation, which is still not available in Harmony.<br />
• Apache Geronimo runs on Apache Harmony with some issues and workarounds [37] .<br />
• Vuze, formerly Azureus, because of unimplemented security classes.<br />
