By the summer of 1992, the team could demonstrate portions of the new platform, including the Green OS, the Oak language, the libraries, and the hardware. Their first demonstration, on September 3, 1992, focused on building a personal digital assistant device named Star7 that had a graphical interface and a smart agent called «Duke» to assist the user. In November of that year, the Green Project was spun off to become Firstperson, a wholly owned subsidiary of Sun Microsystems, and the team relocated to Palo Alto, California. The Firstperson team had an interest in building highly interactive devices, and when Time Warner issued a request for proposal for a set-top box, Firstperson changed their target and responded with a proposal for a set-top box platform. However, the cable industry felt that their platform gave too much control to the user, so Firstperson lost their bid to SGI.

Additionally, the extended precision floating-point types permitted in 754 and present in many processors are not permitted in Java. When generics were added to Java 5.0, there was already a large framework of classes , so generics were chosen to be implemented using erasure to allow for migration compatibility and re-use of these existing classes. This limited the features that could be provided by this addition as compared to some other languages. In most cases, Java support is unnecessary in Web browsers, and security experts recommend that it not be run in a browser unless absolutely necessary. It was suggested that, if Java is required by a few Web sites, users should have a separate browser installation specifically for those sites. According to Richard Stallman, this would mean an end to the «Java trap».
