JITWatch VS MaterialFX

You can kind of do the same as DISASSEMBLE in Clojure.

There are some helper projects like https://github.com/Bronsa/tools.decompiler, and on the OpenJDK JitWatch (https://github.com/AdoptOpenJDK/jitwatch), other JVMs have similar tools as well.

It isn't as straightforward as in Lisp, but it is nonetheless doable.

As you have encapsulated the asserts inside methods, these will be called at runtime with the arguments evaluated (for example, creating that lambda). When assertions are disabled, the C1/C2 may inline the empty method call eventually, but I don't know whether it drops the lambda instantiation as well. You can use JITWatch to see what gets inlined. The general notion though is to not worry too much. Lazy log messages are a common pattern.

You can use jitwatch for this. To see the actual assembly code generated you will also need to use a debug build of the jvm.

If you use Oracle's own IDE, it will support it out of the box, as it already did on Sun's days.

Then there are other ways depending on which JVM implementation is used.

On OpenJDK's case you can load runtime plugin to do it

We use https://github.com/AdoptOpenJDK/jitwatch for this.

If you already know any JVM or .NET language, the first step would be to understand the full stack, you don't need C for that.

Many of us were doing systems programming with other languages before C went mainstream.

What you need to learn is computer architecture.

Getting back to JVM or .NET, you can get hold of JIT Watch, VS debug mode or play online in SharpLab.

Get to understand how some code gets translated into MSIL/JVM, and how those bytecodes end up being converted into machine code.

Languages like F# and C# allow you to leave the high level comfort and also do most of the stuff you would be doing in C.

Or just pick D, which provides the same comfort and goes even further in low level capabilities.

Use them to write a toy compiler, userspace driver, talking to GPIO pins in a PI, manipulating B-Tree data stuctures directly from inodes, a TCP/IP userspace driver.

Not advocating not to learn Zig, do it still, the more languages one learns the better.

Only advocating what might be an easier transition path into learning about systems programming concepts.

You can enable a lot of debug information about how the compiler decides what to do with your code using feature flags like -XX:+UnlockDiagnosticVMOptions -XX:+PrintInlining. If you want to dive deeper into the world of the Hotspot JIT Compiler, have a look at JITWatch.

In what concerns HotSpot, one way would be JITWatch.

You can have a look at the VirtualizedFX which is a virtual flow that is written from scratch and inspired by Flowless. The author Palexdev (I think the person is on reddit), took inspiration from Flowless, and has documented the code quite well. You can have a look and also implement a virtual grid with it such as a GridView. Honestly, I tried making my virtual flow, that is simple with a few classes as possible (with adequate success), and the inspiration came from it. The VirtualizedFX has now been incorporated in MaterialFX which is another main project by the same author.

For a more detailed look, please refer to this link.

Probably MaterialFX, but I haven't worked with it yet.

Unfortunately I'd like to say I have implemented them in my MaterialFX library but I still haven't done it Definitely on the ROADMAP though

You can check the full change list here: Changelog

You can also check out MaterialFX, the MFXTextField has an inbuilt feature to limit the characters

Currently, I use Flowless in my main project, MaterialFX and I really like its performance, its cells' concept, but it has some serious flaws:

There's a way to calculate the minimum required width so that the text is not truncated. Check this utility in my JavaFX library: MaterialFX, LabelUtils

I could add the control to my project MaterialFX, but I recently did a huge update and currently I'm taking a little pause as usual. If you can wait you gave me a good idea and I can definitely add an auto complete field in the ROADMAP list. I can't give any ETA though

Not bad, well done but... Did you know that there's a successor to JFoenix? Take a look at my library here MaterialFX
