SonarQube 8.9 LTS JDK 17

Hi,

I have a question if it is possible to use JDK 17 with source level 15 on SonarQube 8.9 LTS.
When I tested I got exception from FindBugs plugin, and before I request upgrade of plugins I would like to know if it is supported by SonarQube or If SonarQube 9 is required. I totally understand that higher source level require newer SonarQube. Most important for us is to be able to prepare the JDK uplift. Source level is something we can lift later when it is supported.
