Openjdk source11/6/2023 There also is nothing to stop an agent from altering code outside the application, such as code in the JDK itself. While agents were designed with benign instrumentation in mind, advanced developers found use cases, such as aspect-oriented programming, that change application behavior in arbitrary ways. An agent is a component that can alter application code while the application is running these were introduced by the Java Platform Profiling Architecture in JDK 5 in 2004 as a way for tools (notably profilers) to instrument classes. The plan also calls for aligning the ability to load agents dynamically with other so-called “superpower” capabilities such as deep reflection. Other goals of the proposal include reassessing the balance between serviceability, which involves ad hoc changes to running code, and integrity, which assumes running code is not arbitrarily changed, and ensuring that the majority of tools, which do not need to load agents dynamically, are unaffected. These warnings are intended to prepare for a future release that disallows the dynamic loading of agents by default, in order to improve integrity by default. A proposal to prepare to disallow the dynamic loading of agents calls for issuing warnings when agents are loaded dynamically into a running JVM.Goals of the plan include ease of use, comprehensibility, robustness, and performance. A scoped value allows data to be safely shared between components in a large program without resorting to method arguments. Thread-local variables have design flaws including unconstrained mutability, unbounded lifetime, and expensive inheritance. They are preferred to thread-local variables, particularly when using large numbers of virtual threads. Scoped values, also in preview, will enable the sharing of immutable data within and across threads.Goals of structured concurrency include promoting a style of concurrent programming that can eliminate common risks arising from cancellation and shutdown, such as thread leaks and cancellation delays, along with improving the observability of concurrent code. The only significant change this time around is that the StructuredTaskScope::Fork(…) method returns a rather than a Future. Structured concurrency previously was incubated in JDK 20 and JDK 19, released in March and September 2022 respectively it is to be featured as a preview API in the package. This streamlines error handling and cancellation, improving reliability and enhancing observability. Structured concurrency, in a preview stage, simplifies concurrent programming via an API for structured concurrency, treating groups of related tasks running in different threads as a single unit of work.If you would like to contribute or get involved in the project, please visit. Please join us in welcoming the OpenJDK community to GitHub. Now the OpenJDK projects can take advantage of some of the features we built for Java developers on GitHub including free code scanning to look for security vulnerabilities, notifications and remediation of known security fixes as well as semantic code navigation in GitHub (which is powered by the Java based Elasticsearch project). OpenJDK joins a number of our most popular projects here on GitHub all written in Java, including Gradle, Maven, jUnit5, Elasticsearch, Spring, Apache Spark, Selenium, Helidon and more. All of these integrations are now also open source and available in the OpenJDK GitHub organization. To do all this, the team created some fantastic integrations with the GitHub API as part of their Skara tooling. Some of the OpenJDK projects have also been busy adopting GitHub Actions for their CI builds. The team had to build custom CLI Tooling, bi-directional bridging with the OpenJDK mailing lists and integration with the OpenJDK bug tracking system. Like all big migrations, this was much more complex than just doing a hg-fast-export and then a git push. Previously, they were relying on self-hosted Mercurial servers this project involved bringing all of the development team and their tooling over to Git as well as moving the community to GitHub. The ‘Skara’ project has been an impressive effort from the entire OpenJDK community led by the Java Platform Group at Oracle. Therefore it’s a massive honor that we now get to help the team building the future of the Java language. The JDK project is at the heart of the Java community and Java is one of the most popular languages for projects on GitHub. The communities migration effort, codenamed Project ‘Skara’, brought JDK 16 main-line development into GitHub. Earlier this month we were thrilled to welcome the OpenJDK Community to GitHub.
