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.
This was from a Windows agent using JDK 9 that was started from a batch file. The batch file included the line java -jar slave.jar -jnlpUrl http://jenkins.markwaite.net:8080/computer/cb-pc/slave-agent.jnlp -secret my-elided-secret. The same message does not appear when the Windows agent is running JDK 8, whether the master is running JDK 8 or JDK 9.
Stack trace shows:
