ParparVM isn't Mac Only: iOS, Linux, Win32 and embedded targets. We also run on Android and Web. You should look at our benchmarks compared to GraalVM here: www.codenameone.com/blog/java-se...

I didn't measure in JavaSE but we have benchmarks against hotspot which performs well other than startup.
A Smaller, Faster Java Server with a Spring-Style API
Build a smaller native Java service with Spring-style transactions and dependency injection. Inspect the generated code and compare local Linux startup, memory, throughput, binary size and build time.

It tests whether you can spot a compile-time issue before chasing runtime behavior.

Try this study loop:

1. Read a snippet
2. Predict “compiles” or “doesn’t compile”
3. Name the first error
4. Verify it

TIL you cannot access non-constant static fields in an enum constructor (JLS §8.9.2), unlike in a standard class.

This is because enum constructors run during enum class initialization, while non-constant fields are initialized later, creating a forward reference.

docs.oracle.com/javase/specs...
JLS §8.9.2 excerpt: "It is a compile-time error to refer to a static field of an enum class from a constructor, instance initializer, or instance variable initializer in the enum declaration of the class, unless the field is a constant variable (§4.12.4)."

I idolize skipping app startup & snapshot resuming & this seems like the language-non-specific omega tool for that. Building your own Java CDS. Node.js has some similar snapshot tools too but at least for a while they had severe limits.

Spring layout (nothing to do with spring simulation for graph vertex positioning) was actually a lovely piece of work if you were crafting GUIs in the early 2000's.

Constraint solvers and CSP langs have come a long way since then.

Apparently, Java and JavaScript do in fact have something in common.

(Less of an issue now that IDEs can be more verbose and helpful, but still a classic.)

* `System.identityHashCode` calls the `Object` class' default `hashCode()` method, and so does not necessarily return distinct values for distinct objects. However it would apply in most cases according to Java's documentation.
