Manufacturers have been forced to delay volume shipment of their JavaOS-based Network Computers due to "instability" of the JavaSoft operating system.
JavaOS, announced in March, is the primary operating system for machines conforming to the NC specification.
Last week Wyse confirmed volume shipment of its Winterm 4000 NC with JavaOS has been delayed. Wyse was to be among the first to ship an NC using the operating system.
Jeff McNaught, general manager at Wyse, said: "We are experiencing instability issues with the JavaOS." The Winterm 4000 is currently only shipping in small numbers to OEMs and selected customers.
The problems stem from version 1.0 of JavaOS. Although this has now be superseded by JavaOS 1.1, JavaSoft has never formally announced the update.
JavaOS executes the Java environment directly on hardware platforms, without requiring any other host operating system. Wyse said it chose the system because of its close integration with the Java Virtual Machine (VM).
Mark Jordan, vice president for Wyse in Europe Middle East and Africa (EMEA), said JavaOS 1.1 is an improvement on 1.0. "Performance (of JavaOS) is constantly increasing and internationalisation and font support is improving," he added.
Jordan tsaid that he was confident the WinTerm 4000 NC would ship in volume by September 1997.
IBM is also waiting for a more stable version of JavaOS. The company is currently offering a Unix-based operating system with its Network Station.
Chris Gale, JavaStation product manager at Sun in the UK, said the company has not experienced any problems with JavaOS. However he said as the product is in its infancy, "naturally some things will need to be improved".
However, Gale conceded that Sun's current JavaStation NCs are primarily "evaluation" systems. In October, Sun plans to begin volume shipment of a coffee-pot shaped NC, code-named Krupps (above left).
