Wikipedia

OpenJDK is an implementation of the Java Platform, Standard Edition. It is the result of an effort Sun Microsystems began in 2006, four years before the company was acquired by Oracle Corporation. OpenJDK is free and open-source software released under the GNU General Public License (GPL) version 2 with a GPL linking exception, preventing components that linked to the Java Class Library becoming subject to the terms of the GPL license. OpenJDK is the official reference implementation of Java SE

#openjdk across platforms

every network with a public tag surface

Follow #openjdk straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/openjdk
