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

{
        // fill array as a side effect
        if (nativeGenerateSeed(result) == false) {
            // should never happen if constructor check succeeds
            throw new InternalError
                            ("Unexpected CryptoAPI failure generating seed");
        }
}

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
