![]() The OpenJDK project itself is managed on where you can find specifications, source code, and mailing lists, but there are no builds that you can download. You have to decide if you want to stick with the latest LTS version, or if you go with the latest feature release and upgrade every six months.īoth options are okay, but if you’re uncertain, stick with the latest LTS version. If you upgraded to 19 before, upgrade now to 20. If you upgraded to 18 before, upgrade now to 20. You might want to check if you run in any issues with “UTF-8 by Default” by setting -Dfile.encoding=UTF-8 in your current JDK. It is a short term release without significant features. Plan upgrade to version 17 within the next months.Ĭurrent LTS version. Upgrade to a 11 or 17 within the next months! Free updates by Oracle ended, but still maintained by others. Last LTS version under previous release model. ![]() Additionally, there are quarterly bug fix updates.Įvery three years, the September release will be a Long-Term-Support (LTS) release, which gets updates for at least three years. Under the current JDK release model, a new feature release with a new major version number is planned every six months, in March and September. Make sure, you have the latest patch level 17.0.3 or later, due to CVE-2022-21449. ✅ Recommendation: Use Adoptium Eclipse Temurin 17 and ensure that your local version matches the CI and production version. This site gives independent, yet opinionated recommendations. These distributions differ in licenses, commercial support, supported platforms, and update frequency. The OpenJDK is the open source reference implementation of the Java SE Specification, but it is only the source code.īinary distributions are provided by different vendors for a number of supported platforms. Its successor, JDK 21, is due in September, with the feature set due to be frozen on June 8.To build and run Java applications, a Java Compiler, Java Runtime Libraries, and a Virtual Machine are required that implement the Java Platform, Standard Edition (“Java SE”) specification. The current version of standard Java is Java Development Kit (JDK) 20, which arrived last month. ![]() Implementers would be permitted to develop security providers that implement KEM algorithms developed in Java or native code. The plan is to enable the use of KEM in higher-level protocols such as Transport Layer Security (TLS). According to the JEP, the KEM mechanism is simpler and also addresses several disadvantages of the traditional approach.Īlso positioned for standard Java, the KEM API proposal is intended to enable applications to make use of KEM and KEM algorithms such as RSA Key Encapsulation Mechanism (RSA-KEM), Elliptic Curve Integration Encryption Scheme (ECIES), and candidate KEM algorithms for the National Institute of Standards and Technology (NIST) Post-Quantum Cryptography (PQC) standardization process. It differs from the more traditional technique that encrypts a randomly generated symmetric key with a public key. KEM is a modern cryptographic technique designed to encrypt symmetric keys using asymmetric or public key cryptography. The other draft JEP would introduce a Key Encapsulation Mechanism (KEM) API. Appropriate integrity mechanisms in the operating system should always be used to protect the Java platform and Java applications. It is not a goal of the proposal to guard against situations where users compromise the integrity of the Java platform by manipulating the underlying file system, operating system, or hardware, the proposal states. Differentiating use cases where breaking encapsulation is convenient from use cases where disabling encapsulation is essential.Clarifying the Java and non-Java APIs that can break strong encapsulation.Allowing Java to maintain invariants (conditions that always hold) of its own operation as well as that of Java applications that are required for maintainability, security, and performance.
