Java News Roundup
This week’s Java news roundup includes OpenJDK news, GA release of Kotlin 1.5, point release of Eclipse project, Micronaut Coherence 1.0.0-M1, QuarkUS-2.0.0-alpha2, Spring Updates to the project, and developer surveys of Jakarta EE and Payara Platform 2021.
It was a quiet week for OpenJDK JEPs, as there was only one JEP 415. Context-specific Deserialization Filters have been promoted from draft to candidate status. Based on JEP 290. Filtering incoming serialized data, the JEP solves the problem of deserializing untrusted data. An application can invoke a JVM-wide filter factory to select and configure context-specific, dynamically selected deserialization filters for each individual deserialization operation.
Kotlin 1.5.0, the first major release of 2021, was made available by JetBrains this past week and features Java features such as support for logging, sealed interfaces, and inline classes. Over the past few months, the new JVM IR back end has been a work in progress and is now the default compiler for Kotlin. InfoQ has published detailed news coverage of this latest release.
Eclipse has released Mojarra 2.3.15, a maintenance release that fixes about 25 bugs found over 18 months. Mojarra, an implementation of the Jakarta Server Faces 2.3 specification, is an MVC server-side rendering framework. A complete list of bug fixes can be found on the Pull Requests page.
