The test counts all "system" threads before the execution and expects that this number remains the same during test execution.
This makes the test fragile - JVM may start internal threads, some threads may end.

The fix updates the test:

  • the test checks only test threads, and verify that the live threads are reported by GetAllThreads and terminated threads are not reported;
  • dropped "system" thread counting stuff;
  • added proper deallocation of GetThreadInfo results.

Nit: this isn't old style C code, we don't have to declare all variables up front. New variables should be declared where needed.
