From the documentation for java.security.SecureRandom from Java 17 [1]:

> Note: Depending on the implementation, the generateSeed, reseed and nextBytes methods may block as entropy is being gathered, for example, if the entropy source is /dev/random on various Unix-like operating systems.

On current day Linux, /dev/random will only block during bootup, never after it has once started.
