> With NiFi 1.x we used a SecurityManager as part of our Nar Context Class 
> Loading jailing process whereby even spawned threads we'd find the right 
> classloader and pin the context.  Java 21 makes this no longer acceptable so 
> we need a new solution.
> Enter the StackWalker API https://bugs.openjdk.org/browse/JDK-8043814
> Using this we can move to a more efficient and better go forward model that 
> is Java 21+ friendly.
