How does Sun deal with source code where it does not have copyright?
OpenOffice.org includes some source code which has non-Sun copyright notices that is referred to as external source code. The external source code is available under a number of different licenses but is in general freely available, re-distributable and modifiable. Sun has identified URLs where the external code can be sourced, documented the process of downloading the external source and provided a patch process. All external source code retains original license and copyright notices.
