Re: Re: Current BC master (Java) fails tests

I don't know if that would be it, might be, but I would have thought
/dev/random would make the problem worse.

There's two things going on: SecureRandom.getDefaultPRNG() seems to be
returning the SunNative RNG and not the BC one despite the addition of
BC as the number 1 provider in the test, and then it's getting an
IOException because it cannot write the seed material to the device the
native RNG is using (I guess).

Is there another version of BC somewhere - it's a two line test, neither
line appears to be working, and in neither case is it due to anything in BC.

Regards,

David
