java.lang.InternalError: Unexpected CryptoAPI failure generating seed

oracle provided solution, 

The issue seems in the random number generator which is used to seed cryptography . 

1.) Add following system property in setDomainEnv.cmd / setDomainEnv.sh in the JAVA_OPTIONS used on server startup - 

-Djava.security.egd=file:/dev/./urandom 

e.g- 

JAVA_OPTIONS="${JAVA_OPTIONS} -Djava.security.egd=file:/dev/./urandom" 
export JAVA_OPTIONS 


On Windows systems, the URLs file:/dev/random and file:/dev/urandom enables use of the Microsoft CryptoAPI seed functionality.

While generating seed to create random numbers, the exception is being thrown form the method bellow:

            // should never happen if constructor check succeeds

To generate random numbers, SSL security code relies upon entropy on a machine. Entropy is activity of the machine,If entropy is minimal or non-existent, then the random number generator will be slow and security operations may time out.

The class generates seeds for strong cryptographically number generator. It uses two techniques:

Computing current system activity:
Default, produced by counting the number of times the VM manages to loop in a perioud of time. Does not reflect machine load, and a number of sleeper threads are generated to add entropy.
Entropy gathering device:
Alternative, is to acquire material from entropy gathering device, such as /dev/random. By setting the "securerandom.source" security property of the /lib/security/java.security file.
Use the bellow command that starts the Java process as a possible solution:
-Djava.security.egd=file:///dev/urandom
or
-Djava.security.egd=file:/dev/./urandom
