'''Blackdown Java''' was a [[Linux]] [[porting|port]] of [[Sun Microsystems]]'s [[Java virtual machine]], developed by a group of volunteers led by Juergen Kreileder, Steve Byrne, and Karl Asha, and included a team of volunteers from around the globe.<ref>{{cite web

}}</ref> The incident revealed that there were long standing problems between Sun and Blackdown.

Despite widespread confusion, Blackdown was neither [[free software]] nor [[open-source software]]; this was due to licensing restrictions from Sun Microsystems. Its binary redistribution policy allowed it to be pre-installed or included with many [[Linux distributions]] (e.g., [[Gentoo Linux]]){{factcitation needed|date=December 2011}}, whereas at the time, Sun Java's binary redistribution policy did not. Since Java 5, the Operating System Distributor License for Java (DLJ) met many Linux distributions' requirements, lessening the demand for the older Blackdown JVM.

The Blackdown team pioneered Sun's involvement with external, volunteer efforts. Steve Byrne, who was working at Sun at the time, worked with Sun legal to establish an agreement to license the Java test suite for a few Blackdown participants at no cost, and this was used to certify the Blackdown Java implementation as being 100% Java compatible.
