JDK 9, Jenkins 2.60.3 as described in my lts-with-plugins docker instance
While exploring Jenkins 2.60.3 on Oracle Java 9 build 181 (pre-release), it reports illegal access exceptions and warns that a future release of Java 9 will forbid illegal access.
A partial stack trace shows:

[JENKINS-46620] [JDK9] Illegal reflective access from guice 4.0
It is simplest to ignore the message in the log. It is harmless.
If you need to completely avoid it, then you'll need to run Jenkins with Java 8 rather than Java 11.
Testing the dependency-track-plugin with Java 17 GA and Jenkins 2.303.1 fails due to a similar error.

I have also this issue. What can I do to avoid this?
