-------------------------------
Summary: Move to StackWalker API to avoid the no longer allowed
SecurityManager in Java 18+
Key: NIFI-12072
URL: https://issues.apache.org/jira/browse/NIFI-12072
Project: Apache NiFi
Issue Type: Improvement
Reporter: Joe Witt
Assignee: Joe Witt
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.
