> {{java.util.UUID.randomUUID()}} uses a "cryptographically strong pseudo random number generator", which reads from {{/dev/urandom}} (or even {{/dev/random}} in older Java versions), and then computes an expensive cryptographic digest on the bytes it read.
> We don't need a cryptographically strong random number, so we can use {{org.infinispan.commons.util.Util.threadLocalRandomUUID()}} instead.
