Context-specific deserialization filters allow applications to configure context-specific and dynamically selected deserialization filters via a JVM-wide filter factory invoked to select a filter for each serialization operation.New features of JDK 17 include the following: OpenJDK open source builds also are available.

Production builds of JDK 17 can be found at. Developers like to try out the six-month releases while enterprises want to deploy the LTS releases. However, Oracle said downloads of the six-month releases have been steadily increasing. New Relic said 90 percent were running JDK 11 and 10 percent JDK 8. New Relic found that nearly 100 percent of users are running either JDK 11 or JDK 8, the two most recent LTS releases. But that does not include an enterprise production support subscription.ĭata from the customer base of application monitoring provider New Relic, representing tens of millions of production JVMs, show that LTS releases have almost unanimous deployment.

With JDK 17, Oracle will allow free use of Oracle JDK binaries in production for three years, one year past the next LTS. The next LTS release will be Java 21 in 2023. More frequent LTS releases will provide faster access to new features for companies that just want to use the LTS releases, Georges Saab, vice president of Oracle’s Java platform group, said. JDK 17 features everything that has been added since the last LTS release, JDK 11, which arrived three years ago. Non-LTS releases get six months of support from Oracle.Īmong the new capabilities in the new version of standard Java are context-specific deserialization filters support, which is a security enhancement, and a preview of pattern matching for switch statements. Oracle also announced that LTS releases, which receive at least eight years of product support, henceforth will arrive every two years, as opposed to the three years between releases in the past. Java 17, a new long-term support (LTS) release of standard Java, is now available for production use.
