Is it ok to use NativePRNGNonBlocking SecureRandom for making jwt?

I'm developing jwt auth feature with Spring WebFlux. And, I found the blocking calls in jjwt library by using BlockHound.

The reason of blocking calls was SecureRandom use /dev/random to make random number in default on Linux system.

To prevent this, I'm considering to use SecureRandom.getInstance("NativePRNGNonBlocking") that uses /dev/urandom instead of /dev/random.

Is /dev/urandom is safe enough to make jwt???
