Description

ThreadLocalRandom is a combination of ThreadLocal and Random classes, which is isolated to the current thread. Thus, it achieves better performance in a multithreaded environment by simply avoiding any concurrent access to the Random objects.

I also had a conversation with a Oracle Java engineer that indicated that ThreadLocalRandom is preferable with new development.
