Apache Felix
Apache Felix is an open source implementation of the OSGi Core Release 6 framework specification. The initial codebase was donated from the Oscar project at ObjectWeb. The developers worked on Felix for a full year and have made various improvements while retaining the original footprint and performance. On June 21, 2007, the project graduated from incubation as a top level project and is considered the smallest size software at Apache Software Foundation.
