What are the plans to to use Java11 in future MATLAB releases? So far is still using Java 1.8, but Java 11 is now standard default version at many Linux distributions.
Is there any info regarding posibilities to call compiled Java (v1.8) jar files from MATLAB when MATLAB switch its internal Java to the v1.11?

@Michal sry, I thought I did, I don't get a lot how this platform works. Thanks!

@Michal at least, supporting Java 11 means that it's post java-modules era, so what we are trying to do now is to have just one module that is compatible with matlab, and all the others that are more recent, so that at least when interacting from Java you can actually use recent Java versions (the other way around is still problematic if you go above Java 11).
Hopefully future updates will be faster, the critical one was moving from java 8 to 9, where most companies got stuck.
Maybe in 2024 they could switch to Java 17, who knows :)

Thanks again @Ennio Visconti ... This is really good news. I should read release notes more carefully :)

Mathworks will never be switching to Java 11.
Mathworks is engaged in a multi-year process of getting rid of Java for their tools and toolboxes.
The whole uifigure / App Designer exists to get rid of Java.
Why is MATLAB not doing minimal updates to keep current while still proceeding with conversion efforts? It is because every version after the current version requires that end users pay Oracle a per-desktop license fee.
... No, I do not mean a per-user license fee, I do mean a per-desktop license fee. Each virtual machine must be licensed separately, no matter how long the virtual machine lasts. Also, as the language of the license is not specific about what a "desktop" is, it could certainly be interpreted that if you use the MS Windows "switch desktop" feature or the MacOS multiple-desktop feature, that you must license Java for each one of those views.
Historically Oracle only charged fees for the Developer version, but they switch to charging end users as well. And they have a reputation for being litigation-happy.

The OpenJDK is always available for Matlab to use, instead of the Oracle JDK. Your point is moot.

LOL, it's Oracle licensing. You'd have to hire a consultant just to figure out how much it's actually going to cost you.
