Summary of Behaviour:

A.   OpenJDK 7 b65.  

1.   Default in java.security is securerandom.source=/dev/urandom   
2.   If securerandom.source=/dev/urandom, NativePRNG is used, SecureRandom.nextBytes() is non-blocking via /dev/urandom ; SecureRandom.generateSeed(x) is blocking via /dev/random
3.   if securerandom.source=/dev/random, then SHA1PRNG is used.  Initial seed is blocking via /dev/random.   No other accesses.
4.   If securerandom.source=/dev/./urandom then SHA1PRNG is used.  Initial seed is non-blocking via /dev/./urandom.  No other accesses.

B.   Oracle JDK 8 b25.
