Local fix

Problem summary

• The SecureRandom instance using the SHA1PRNG algorithm crashes
  on the Windows platform when generateSeed is called with an
  argument of 0.
  

Problem conclusion

• IBMCAC has been updated to handle the 0 value when it is passed
  as an argument to SecureRandom.generateSeed.
