Hello,
I am writing a plugin to report errorprone findings in SonarQube.
Since errorprone uses some internal JDK API (and since JEP-396) it needs the JVM to start with some options such as: --add-exports=jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED.
I have integration tests running the plugin an analysing a sample maven project, it is working as expected on SonarQube 10.4 however on 10.6 (or 10.7 or 24.12) I’m getting an error indicating that the JVM options were not enabled:

Indeed when comparing the logs I see that when running on SonarQube 10.7 the scanner seems to provision a JVM:

When running on 10.4 there’s no mention of provisioning a JRE:

Can you please advise if the scanner is indeed forking a new JVM on newer versions of SonarQube?
I suspect the issue might be that the JVM is a JRE (not a JDK), so it is missing the javac module.
Even it is a JDK, I think it would need the extra --add-exports options. Is there a way to start that JVM with plugin-supplied arguments?
