Open JDK : What is it?
Open JDK is an open-source software envirnoment specific to Java. This is the free version of JDK (Java Development Kit). Its creation sterns from an inconsistency in the very nature of Java. Indeed, to be completely free (open-source), a software must check two conditions:
- Comply with a licence approved by the Free Software Foundation (GNU)
- Make sure that all the dependencies are also free.
OpenJDK is a community project made to create a fully free Java development environment. That community is made up of individuals contributing to Java or JDKs but, it is also sponsored by big companies as Red Hat / IBM / Azul Systems / Apple or SAP.
