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.
Yes I was sure we had agreed to remove that and I don't see it in Oracle JDK
so perhaps it is only in OpenJDK launcher?
Hi David,
not sure what you mean? Does the Oracle JDK come with another launcher
compared to the OpenJDK?
No - I was confusing myself.
I've just tried with the latest EA build 170 (which I assume is an
Oracle JDK) and I see exactly the same error:
Ok. I see now that we still have the confusing error message depending
on exactly when the exception is thrown.

So what do you mean when saying that you don't see it in the Oracle JDK?
