Runtime instrumentation in Java – with no frameworks at all.

I wrote a REST service using HttpServer and injected logging logic at class-load time using a custom Java Agent and the Instrumentation API.

I always forget how to create a #JavaFX ComboBox and configure it to show a specific field of an object in the ComboBox's opened and closed states. So, I wrote a tutorial, hoping my future self will remember that I blogged about it the next time I need this functionality.

Just published a longform article on parallel collectors in Java Streams.

Covers correctness, performance, pitfalls
Custom collectors with CONCURRENT semantics
JMH benchmark

TL;DR: .parallelStream() is not a magic wand.

Dear Gradle, Why So Stubborn?
Do I do something wrong?

Watching juniors try to set up a project and being greeted by cryptic stack traces like it's some kind of initiation ritual.

`Unsupported class file major version 61`
`invalid CEN header zip64 no access package`, ...

Java can compile code for older versions just fine.
It's literally designed for that.
Oh why, must Gradle behave like a bitter librarian who refuses to hand over a book unless I whisper the exact Dewey Decimal Code?
Every other Language will laugh again at java, seeing this.

Why is Gradle bound to a java version? And if Gradle knows it needs Java 11… why doesn't it just do this for me?
Like using `/usr/libexec/java_home -v 11` in background?

Is there a clean way to force Gradle into submission without adding another tool like SDKMAN or jabba or YunaBraska/gradle-java-fix or whatever the trendy painkiller of the week is?
