> Yes, the exploded case should be okay. However, if java.nio.file.spi.DefaultFileSystemProvider specifies a class in a JAR file that is on the class path or module path then you'll run into this issue.  Setting the security manager on the command line will trigger this occur at VM startup.

I had filed an incident report against my application for these errors when I was asked to verify the security manager on command line fix. 
Having no simple test case the bug report was just closed as unable to reproduce.
If https://bugs.openjdk.java.net/browse/JDK-8263940 <https://bugs.openjdk.java.net/browse/JDK-8263940> is assumed to still cover the current situation that’s fine. Otherwise there is no bug report I know of to track the current errors.
