In our test library, there is a TODO item:

 public class LocalRandom {
     static {
        // ensure seed got printed out
        // TODO re-enalbe when monitor doesn't require to pin thread
        // Utils.getRandomInstance();
     }

That TODO comes from the original Loom integration:
 8284161: Implementation of Virtual Threads (Preview)

As we did JDK-8337395, this does not look relevant anymore.

Enabling this one would start printing random seeds, which is useful for test debugging.
