Volker - one suggestion for your experiments is to change your JDK 8 
security properties file (java.security) to add 
"com.sun.crypto.provider." to the value of the "package.access" 
property. That should mean you will get the same AccessControlException 
with JDK 8 as you do with JDK 9. It may help to reason about the JDK 8 
behavior, including what is triggered by verification, before looking at 9.

On the "Error: A JNI error has occurred, please check your installation 
and try again" message. It's not core to your questions of course but I 
agree it is confusing. Ramanand Patil had a number of attempts on 
core-libs-dev to improve this and it may be that more is needed there.
