Apache Log4j 2
Apache Log4j 2 is an upgrade to Log4j that provides significant improvements over its predecessor, Log4j 1.x, and provides many of the improvements available in Logback while fixing some inherent problems in Logback's architecture.
Project mention: Reduce Security Risks by Keeping Dependencies Up-To-Date with GitHub Actions and Dependabot | dev.to | 2022-03-10Almost nothing is more ubiquitous in applications than logging libraries. No matter which type of application - hastily thrown-together prototypes, decades-old enterprise monoliths, newly built event-driven serverless apps - there is always the need to log. Even in non-production-grade applications where standard observability patterns such as monitoring and alerting might not be applied - logging is usually always used. Log4j has been without a doubt one of the pioneers in the logging framework sphere and continues to be widely used today making the recent discovery of a zero day exploit in Log4j a good time to highlight how important it is to keep all dependencies of your applications up-to-date at all times.

swagger2markup
A Swagger to AsciiDoc or Markdown converter to simplify the generation of an up-to-date RESTful API documentation by combining documentation that’s been hand-written with auto-generated API documentation.
Project mention: API documentation platforms/authoring stacks | reddit.com/r/technicalwriting | 2021-09-07I'm already up to my elbows in AsciiDoc/Antora building a new online help platform, and I noticed that Swagger2Markup exists. No idea if it's any good, but I might be able to integrate it into my existing workflow and spit out some usable static content at the other end...

I would like to introduce an open source library I worked on under the Apache 2.0 license called DockerSandbox. It provides a wrapper API to the Docker Java Client at https://github.com/docker-java/docker-java that allows code to be executed in sandbox containerized environments. It provides similar functionality for Java that StepikOrg provides for Python with epicbox at https://github.com/StepicOrg/epicbox.

Discord4J
Discord4J is a fast, powerful, unopinionated, reactive library to enable quick and easy development of Discord bots for Java, Kotlin, and other JVM languages using the official Discord Bot API.

Multitenant backend server for building web and mobile apps rapidly. The backend for busy developers. (self-hosted or hosted) (by Erudika)

A new version of DeepfakeHTTP is out! I decided to add a new --dir option, allowing to host static content as static servers do. However, unlike regular static servers, DeepfakeHTTP can also host executable stuff, such as shell scripts or JavaScript. In order to have JavaScript executed on the server side you need to specify 'use server' at the beginning of the code (similar to the well-known 'use strict').

On a previous project, I got to use a nifty tool called OpenTest to orchestrate test automation on an Android app. It's not a widely popular framework yet, but I hope it grows because it solves one particular problem quite well. OpenTest enables a QA team to write tests once that can run across multiple environments and platforms. It's a solid tool if you're looking to do something like automate an iOS and Android app that have identical UIs, or just want a shared language for your web and mobile app testing frameworks. OpenTest is also written in YAML, so it's approachable for even quite junior SDET teams.

even according to XSeries it should be that...

You'd probably want to look into forking https://github.com/Oshan96/CustomStage and modifying it to suite your needs.

I recommend you try the library LibGui. It has a decent wiki, easy to use, and is great for widgets. Link: https://github.com/CottonMC/LibGui

revapi
Revapi is an API analysis and change tracking tool written in Java. Its focus is mainly on Java language itself but it has been specifically designed to not be limited to just Java. API is much more than just java classes - also various configuration files, schemas, etc. can contribute to it and users can become reliant on them.
