There are several open source tools for Java (Eclipse, Visual Studio plugins, Netbeans and others). The reason I don't use them is not because they are bad, but because IntelliJ is so much better. I even use IntelliJ Ultimate for non J

I think it has a lot to do with work culture. Many tend to mimic what others are doing in order to not stick out. At my previous job some were able to change that by consistently using "modern" features of Java. It inspired others

I haven't used it myself, but I know there is a plugin for a Maven build cache. It seems like it should improve incremental builds https://maven.apache.org/extensions/maven-build-cache-extens... > Incremental b

The JVM tends to use as much memory as it can for performance reasons. It is not a reliable indicator of how much memory it actually needs. Why spend resources on clearing memory if there's still unused memory left? If memory is an i

I think named parameters would be a great addition For now, I use Lombok's @Builder annotation. It makes it much easier to create and copy a record, where non-assigned attributes are set to default. Example: var bmw = Car.builder(

That's why moduliths are becoming more popular. These are basically monoliths that enforce structure. The other advantage is that each "module" can be extracted as a micro-service later without much work.

The Java library actually supports this case. It may not have the convenient "years" method directly, but you can add an arbitrary unit of time quite easily Example with duration: Duration.of(1, ChronoUnit.YEARS) Example

I'm not sure if I understand your point, but I haven't seen any NIH at the places where I have worked. We have been encouraged to use popular stable libraries when possible. Java has several 3rd party dependencies that are expecte

If I understand your use case, most loggers (like Logback) have the possiblity to automatically include the name of the method that called the log-statement. Logback even supports including the call chain in the output, so you could include

Lombok can be used for more than just getters/setters. I personally use the @Builder annotation on records with more than 3-4 fields. I find it much more readable than a long list of arguments to the constructor. It also makes it eas

I've gotten 100x improvement with no code change by just adding an index in the database table. An inexperienced developer might have blamed the database and insisted on moving to NoSQL because of "web scale". If they got the

They wrote it from scratch with the benefit of all the knowledge they had gathered after running the old system for years. A 2X improvement would not be surprising to me, even if they had rewritten it in the same language. . According to ot

I'm curious about how you plan to work on checked exceptions. If it's just about ignoring forced exception management, Lombok provides the @SneakyThrows annotation. I would need something more before I add a new type of extension.

Spring Modulith is trying to enforce strict module boundaries. I haven't yet tried it myself, but it looks promising: https://spring.io/blog/2022/10/21/introducing-spring-modulit...

At one of my previous jobs, they had a "BOM" that each service inherited from. This contained most of the core dependencies (Spring, database drivers, logging, monitoring, auth, service discovery etc.) with a default configuration

There are tools for enforcing boundaries. One name for this is "Modulith" where you use modules that have a clear enforced boundary. You get the same composability as micro-services without the complexity. Here's how Spring
