ThreadLocal is basically a middle path. Creating a RandomIO to for access /dev/random each time > Would it be easier to remove the state (singleton, thread local) caching > completely?

ThreadLocal is basically the middle path. The singleton approach only needs one open and close, however it would require threads to be sync'ed to access /dev/(urandom) ------------- PR: https://git.openjdk.org/jdk/pull/11069
