Its an VPS running under openvz

A DESCRIPTION OF THE PROBLEM :
When I execute the command:

cat /proc/sys/kernel/random/entropy_avail

I'm always getting 0 (zero) as result.

When the java code calls java.security.SecureRandom.generateSeed(int), the code stay blocked (frozen).

Checking with VPS provider, I was notified that /dev/random was disabled.

I believe that JVM should throws an Exception or use a different approach to generate seed

REGRESSION. Last worked in version 8u77

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Disable /dev/random and call the mentioned method abova.


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
I have asked to VPS provider enable /dev/random
