When kapt complains, that it can't find a 
tools.jar
(which is correct, because I'm not using Java 8 anymore) – what doesn't work then? Any way to suppress that warning (I'm using Maven)?

Hi! Can you please share full warning message?. Also, do you build your project via JPS or via “delegate to Maven”?

I'm using Maven on the command line. Full message:
Copy code
[INFO] --- kotlin-maven-plugin:1.5.0:kapt (kapt) @ simulator ---
[WARNING] 'tools.jar' was not found, kapt may work unreliably

That's with AdoptOpenJDK 11, so there is indeed no 
tools.jar
and the reflection warning is probably also expected.

Thank you, I’ll take a lookloading
@hho, hi! Thank you for your report! I’ve created issue on youtrack : https://youtrack.jetbrains.com/issue/KT-47110 You can subscribe and you will be notified about updates

Nice to see that this is considered for fixing. What I find more troubling is that when using AdoptOpenJDK 16, the (deprecated) switch 
-Dillegal-access=permit
has to be set in order for kapt to work. This means that kapt will cease to work with JDK 17, 18 or whenever that option will be removed.
