Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Logging in your API

Spring Boot logging with Loki, Promtail, and Grafana (Loki stack)
This is a GitHub link to my demo app. It’s simple Spring Boot web app used to debugging various stuff. There are many ways to configure JSON logging in Spring Boot. I decided to use Logback because it is easy to configure and one of the most widely used logging library in the Java Community. To enable JSON logging we need to add below dependencies.

5 Best Logging Solutions for Java
Logback(https://logback.qos.ch/) is another non-commercial Java logging framework. It labels itself as a successor to the previously discussed Log4j framework.

Log4j: The Pain Just Keeps Going and Going
> Then apache decides to put new people on log4j, do a backward incompatible v2 design that nevertheless is worse than slf4j. Why?
slf4j itself isn't a logging framework. It's a facade to logging frameworks.
Simple Logging Facade for Java ( https://www.slf4j.org )
It needs a logging framework behind it - log4j, log4j2, logback, commons, JUL.
The question is "why do log4j2?"
Logback went from the log4j1.x path ( https://logback.qos.ch )
Log4j2 has a lot of features that weren't present when the project started ( https://en.wikipedia.org/wiki/Log4j#Apache_Log4j_2 ).
There is a licensing difference between Logback (LGPL) and Log4jx (Apache Commons).

E2E-Testing in CI Environment With Testcontainers
Also, I'd like you to pay attention to the log consumer. You see, when the E2E scenario fails, it's not always obvious why. Sometimes to understand the source of the problem you have to dig into containers' logs. Thankfully the log consumer allows us to forward a container's logs to any SLF4J logger instance. In this project, containers' logs are forwarded to regular text files (you can find the Logback configuration in the repository). Though it's much better to transfer logs to external logging facility (e.g. Kibana).

How to Check if a Java Project Depends on A Vulnerable Version of Log4j
This shows that the MariaDB JDBC driver uses Logback as a logging framework. Although Logback is not affected by Log4Shell, it has a related vulnerability (of much lesser severity, no need to panic) fixed in version 1.2.8 and 1.3.0-alpha11. I checked the version used by the connector and found that it used 1.3.0-alpha10. Even though Logback is included as a test dependency in the MariaDB driver, I sent a pull request on GitHub to update it. I encourage you to do the same in any open-source project you find and that includes a vulnerable dependency.

Migrating off of Log4j 2.x
Dependencing on the project, changing the logger might range from easy peasy to a multi-week task. I'm ready to bet that in many (most?) cases, it'd actually be quite easy, so let's explore how to do it, using Logback as the target (there aren't that many alternatives actually).

Replacing Logging APIs with java.lang.System.Logger
The main features that I've heard being asked for are handled by API decorators, such as Google's Flogger. I have personally not run into limitations that caused me concern about the speediness of slf4j2.

How does one separate security-critical parts to Rust in practice?
Yeah, I think switching to e.g. Flogger would be much more practical than rewriting it in Rust.

“Open Source” Is Broken
Why do you think they're using log4j to any significant extent? I'd be a bit surprised if they ever did rather than rolling their own, because for something this simple the cost of writing your own is far cheaper than dealing with a dependency. We're not talking about Linux or Clang here...
In particular, from https://github.com/google/flogger#yet-another-logging-api:
> Flogger is now the sole recommended Java logging API within Google.
