2017 We'll continue to ship proprietary "Oracle JDK" builds, which include "commercial features" [7] such as Java Flight Recorder and Mission Control [8], under a click-through binary-code license [9]. Oracle will continue to offer paid support for these builds. After JDK 9 we'll open-source the commercial features in order to make the OpenJDK builds more attractive to developers and to reduce the differences between those builds and the Oracle JDK. This will take some time, but the ultimate goal is to make OpenJDK and Oracle JDK builds completely interchangeable. 12 / 13
