`InnocuousForkJoinWorkerThread` (used by `ForkJoinPool.commonPool()` under certain security configurations) throws `SecurityException` when `setContextClassLoader` is called. This crashed the cleanup thread, disabling phantom-reference-based leak detection for the rest of the JVM lifetime.
    
Wrap the call in try-catch since it is best-effort: `ForkJoinPool` does not inherit `contextClassLoader` from the submitting thread, but custom thread factories might, so we still attempt to nullify it.

I couldn't make the test run with the SecurityManager as Gradle overrides it.
