Does anyone have information about when the GraalVM native image will catch up with Java 13,14? I found no public roadmap or plans?

I studying a lot about Dart and Flutter and got some questions regarding the Dart Runtime and VM:
What is the Dart Runtime?
What is the difference between the Dart Runtime and the Dart VM?
The dart code compiled to AOT can be considered the same process of Java compiling to Bytecode, since it needs a VM (or runtime) to run on a machine?
Our video from I/O 2019 explains a lot of this – https://www.youtube.com/watch?v=J5DQRPRBiFI
I am using ant script for Sonar code scan .Currently with 'sonar-ant-task-2.2.jar' i am able to execute scan for Java 7.
With Java 8 which version of sonar-ant-task need to be used ?
Thanks & Regards

Read point #2 of Prerequisites at documentation. Use At least the minimal version of Java supported by your SonarQube server is in use.
See this, any JRE v8 will do.
If you have a look at the documentation of the latest scanner you will find this Prerequisites section:
SonarQube is already installed
At least the minimal version of Java supported by your SonarQube server is in use
The language plugins for each of the languages you wish to analyze are installed
You have read Analyzing Code Source.
Ant 1.7.1 or higher
So using Java 8 is not a problem if you are using SonarQube 5.6+ and using the latest scanner will resolve some issues (see the changelog).
I recently use the pre-built OpenCV 3.1.0 on Windows which was downloaded from here. Actually, I followed the official installation.
The thing is that I find that the VideoCapture module of pre-built OpenCV processes video very slowly. It seems that it has no support of ffmpeg. And I find the official note:
To use the OpenCV library you have two options: Installation by Using the Pre-built Libraries or Installation by Making Your Own Libraries from the Source Files . While the first one is easier to complete, it only works if you are coding with the latest Microsoft Visual Studio IDE and doesn't take advantage of the most advanced technologies we integrate into our library.
It makes me curious about what is the actual build configuration of pre-built OpenCV 3.1.0 (or other versions) on Windows. No supports of TBB, IPP, Eigen, CUDA, etc...? I didn't find any clue on the internet. Anyone knows?
The current google native client port of OpenCV does not utilise TBB. It says here TBB can be built under NaCl.
Is there an official port, or has anyone successfully built TBB under NaCl?
Thanks :)
For now there is no official port of Intel TBB for NaCl, and the project team at Intel (which I work in) is unaware of any unofficial one either.
I am setting up a new project (java backend + dart frontend).
On client side I plan to use stagexl as a gaming framework. On server side I will use Google App Engine. (Plus Gradle and GIT ...)
Yesterday I followed http://blog.dartwatch.com/2013/01/integrating-dart-into-eclipse-and-your.html for installing the dart eclipse plugin but I get lots of error popups all the time.
Problems occurred when invoking code from plug-in: "org.eclipse.ui.views.properties.tabbed".

A beer or two to the one who helps me!
Instead of installing Eclipse and then installing the Dart plugin, I recommend you to download the Dart Editor from their page
That is an already fully functional Eclipse instance prepared for dart usage.
From there, you can create a new project and they will give you some pre-defined templates.
