 By the appearance of OpenJDK 6 in May 2008, less than 1% (the SNMP implementation, which is not part of the Java specification) remained, making it possible to build OpenJDK without any binary plugs.The binary plug requirement was later dropped from OpenJDK 7 as part of b53 in April 2009.This was made possible, over the course of the first year, by the work of Sun Microsystems and the OpenJDK community.
