MSJVM Situation
Microsoft JVM SituationMicrosoft JVM Situation
In a settlement agreement reached in January 2001 to resolve a dispute over Microsoft's distribution of its Java implementation, Sun and Microsoft agreed to limit the duration of Microsoft's use of Sun's source code and compatibility test suites to support the MSJVM until January 2004

Microsoft/Sun ExtensionMicrosoft/Sun Extension
Sun and Microsoft have agreed to extend Microsoft's license to use Sun's Java source code and compatibility test suites until September 30, 2004, and gives Microsoft the ability to address potential security issues, effectively giving customers another year to manage the transition
