Caused by failing unit tests that involve "java.security.SecureRandom" 
as
the source of randomness.

The tests use a _fixed_ seed, yet the output of the RNG is random.
On my machine, the "getAlgorithm()" method returns "NativePRNG"; I 
guess
that it is a non-deterministic generator.

IIUC, the failure indicates that the RNG is not quite uniform (the 
tests
fail much more often that the 0.01 probability reported by the 
message).

Should I just delete the "RandomUtilsDataGeneratorJDKSecureRandomTest"?
Other suggestions?


Thanks in advance,
Gilles
