### What does this PR do? Adds a JUnit 5 regression test that demonstrates a thread leak in `LoadSimulationController` due to an unclosed static `ExecutorService`. ### Why is this needed? `LoadSimulationController` declares a private static cached thread pool (`Executors.newCachedThreadPool()`) with no shutdown path. In embedded or containerized test environments, the non-daemon threads can outlive intended usage and delay or prevent clean JVM shutdown. ### How was this tested? A new JUnit 5 test uses reflection to access the static executor, submits a task to force thread creation, and asserts that a non-daemon executor thread is alive afterward. ### Follow-up I will push a subsequent commit on the same branch that introduces proper executor lifecycle management (instance-scoped executor + explicit shutdown) and updates the test expectation accordingly. -- This is an automated message from the Apache Git Service.
