Free Java implentations.

Paul Dwerryhouse writes "Infoworld have done a report on the existence of a number of free Java Virtual Machine implementations. Both Kaffe and Japhar have been mentioned. Mind you, I'm always surprised by the way journals describe such products as "weakening Sun's control of Java" - I'd always thought the point of Java was that Sun would make their money by licensing the name and by "providing the best Java environment" - ie, enabling real competition."
