   * For now, we continue using it to clean up under older JDKs.

   * Our usages should at least be *relatively* safe: Typically, threads started by a test are dying
   * at the end of the test, so there is no object state put at risk by stopping the threads
   * abruptly. In other cases, a test may put a thread into an uninterruptible operation
   * intentionally, so there is no other way to clean up these threads. (The better solution,

When adding new tests:
1. Follow the existing naming convention: `test_<method>_<scenario>_<expectedResult>`
2. Add clear JavaDoc comments explaining the test purpose
3. Ensure tests are independent and can run in any order
4. Clean up resources in finally blocks or use try-with-resources
