Relearning Java Thread Primitives
I’ve coded in Java since the first beta, even back then threads were at the top of my list of favorite features. Java was the first language to introduce thread support in the language itself, it was a controversial decision back then. In the past decade, every language raced to include async/await and even Java had some third-party support for that… But Java zigged instead of zagging and introduced the far superior virtual threads (project Loom). This post isn’t about that.

Managing Cluster Membership with Etcd
Given our new functionality to update the membership list, we can create a new test case where two nodes join the cluster and expect that to be reflected in the local state of each node eventually. Thanks to the Awaitility DSL we can conveniently wait for the eventual update to happen.

Mockito and non-debuggable testBuildTypes
For those using a "release" testBuildType for integration tests, what does your mocking setup look like? My app is stuck on Mockito 2.23.4, because higher (> 1.8.12) versions of Byte Buddy required beyond that point [do not play nicely with non-debuggable APKs](https://github.com/mockito/mockito/issues/2302). Solutions I've considered so far:
- Mockito - Most popular Mocking framework for unit tests written in Java

Reverse engineering Mockito. Part 2. Dynamic dependency injection
The code is pretty self explanatory but here's a quick run down. o.getClass().getDeclaredFields() gets us an array of all the fields. We then have a enhanced for loop that loops over the array. Check if the field is annotated field.isAnnotationPresent(Gucci.class). If it is then we set its modifier to true with field.setAccessible(true);. If we don't do this and the field is private we will get an error. Then we get the binary name of the field, field.getGenericType().getTypeName();, remember its just the package and the class name. Lastly we set the value of the field, field.set(o,dynamicInjection(classLoader,binaryName). With that we have now created a dependency injection annotation with the Junit 5 extension model. Now I am sure you can see the tower of exceptions, which is obviously not ideal. I'm not sure how I want to handle all the exceptions yet. However, I will be digging around the Mockito code base to see if I can find how they handle all their exceptions.

Writing Apache Parquet Files
Hi, I've been trying to write parquet files on android for the past couple of days, and have really been struggling to find a solution. My original hypothesis was to just use the java parquet implementation (https://github.com/apache/parquet-mr), but I've since realized that not all java libraries play well with Android. I've gone through essentially dependency hell trying to franken-fit the library into my project, and imported as much as i could before hitting walls such as this one (https://github.com/mockito/mockito/issues/841).
What are some alternatives?
Spock - The Enterprise-ready testing and specification framework.
WireMock - A tool for mocking HTTP services
REST Assured - Java DSL for easy testing of REST services
MockServer - MockServer enables easy mocking of any system you integrate with via HTTP or HTTPS with clients written in Java, JavaScript and Ruby. MockServer also includes a proxy that introspects all proxied traffic including encrypted SSL traffic and supports Port Forwarding, Web Proxying (i.e. HTTP proxy), HTTPS Tunneling Proxying (using HTTP CONNECT) and SOCKS Proxying (i.e. dynamic port forwarding).
Selenide - Concise UI Tests with Java!
Testcontainers - Testcontainers is a Java library that supports JUnit tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.
