BZ #60: SecureRandom.nextBytes() throws InternalError: URLSeedGenerator file:/dev/random generated exception: Invalid argument

Status fields:

This simple testcase:

        SecureRandom sr = new SecureRandom();
        byte[] seed = new byte[20];
        sr.nextBytes(seed);

throws this exception with OpenJDK libraries:

I investigated this bug more deeply and this is a more common problem: we don't use
OpenJDK's HPI.  I have already started to fix that.  A patch is coming soon.

This changeset:

http://mips.complang.tuwien.ac.at/hg/cacao/rev/fceac7c38a1b

adds the initialization and usage of the HPI.  The bug is fixed.
