-----------------------------------------------------------------
I don't think this will ever be fixed in the JDK.
Those warnings still appear with java 9.0.1 if you run {{la}} for example which
shows the {{ShellTable}} list for bundles, you should see the warning.
Each of these warnings needs to be fixed by somehow removing the reflection
code, which may not be easy.
The problem won't be fixed by the JDK. At some point, the default will be
changed to {{--illegal-access=deny}} which will break the code. See
