Transvirtual Technologies Inc., a small start-up company in Berkeley California that is funded by Microsoft Corporation, has developed a clone of Java called "Kaffe." The clone allows developers to write Java applications that run under Windows only and take advantage of Microsoft's Windows-specific extensions to Java. From Sun's standpoint, this is yet another chink in the armor of Java, which was designed to run equally well (or "equally poorly" as the case may be) on any platform, not just Windows.

Because of a recent ruling in its legal battle with Sun, Microsoft is unable to develop such technology itself. However, Transvirtual Technologies is not affected by the ruling and it continues to fine-tune the clone.

The timing of this announcement isn't surprising: Sun's JavaOne trade show begins this week
