The Java 11 update, however, included them in OpenJDK’s feature set, making Oracle JDK and OpenJDK now nearly identical in function. Systems with frequent updates like this enhance overall security despite the fact that more people have access to the source code.įeatures such as Application Class-Data Sharing, Z Garbage Collector, Java Mission Control, and Flight Recorder once belonged only to Oracle JDK. At that point, older versions become obsolete. Oracle offers long-term support for these releases, whereas OpenJDK does so only until the next update. While OpenJDK has announced plans to provide releases every six months, Oracle JDK plans to update every three years. One of the most striking differences between Oracle and OpenJDK is the intended release schedule. While access to specific tools may require a fee, basic access to the source code is available for no charge. On the other hand, OpenJDK provides free feature updates every six months and requires no subscriptions. Without this license, users have no access to upgrades or product support. Whereas Oracle JDK was once available for free, it now requires developers to pay for access to Sun’s official implementation license. In early 2019, Oracle made a significant change to its pricing policy. What Are the Advantages of an Open Source JDK?Īside from gaining access to original source code, switching to OpenJDK offers users unique features, better prices, and more opportunities for collaborative development. Oracle stressed that developers could expect to see regular feature updates from JDK Open Source from that point forward. Oracle included the Java community in its updates to produce a more comprehensive open product. The product was initially released in 2007 as an implementation of the Java SE Platform Edition. When Oracle purchased Sun in 2010, it opened up the development of OpenJDK, Java’s version of open-source software. Open source code affords developers more opportunities to collaborate with other knowledgeable professionals to create high-quality software. Software is considered open source when its original code is free and accessible to everyone. The kit’s environment differs from the Java Runtime Environment, which allows users to run applications only those looking to develop apps in Java require a JDK. What Does JDK Mean?Ī JDK, or Java Development Kit, is a toolbox that enables software developers to run and create code in Java. Fortunately, migrating to JDK Open Source requires minimal effort and costs little to nothing. With OpenJDK, developers can move toward a system of increased cooperative work and better implementation practices. Countless software developers rely on Java when programming, and OpenJDK is the latest software to make working with code even more accessible.
