This solves some of the test failures I've been seeing. +1 to commit!

> Key: SOLR-2019
> URL: https://issues.apache.org/jira/browse/SOLR-2019
> Project: Solr
> Issue Type: Bug
> Reporter: Michael McCandless
> Fix For: 3.1, 4.0
>
> Attachments: SOLR-2019.patch, SOLR-2019_insecure.patch
>
>
> I'm hitting this Jetty issue when running Solr's tests that spawn a Jetty:
> http://jira.codehaus.org/browse/JETTY-331
> It seems to be caused by this root cause:
> http://bugs.sun.com/view_bug.do?bug_id=6202721
> Whereby, somehow, Jetty is trying to use cryptographically secure source of
> randomness to seed seed its HashSessionIdManager. My box doesn't have enough
> entropy so the read blocks for sometimes 10s of seconds!
> If I forcefully symlink /dev/random -> /dev/urandom, that fixes the hang.
> Likewise, if I edit the JRE's java.security to set
> securerandom.source=file:/dev/./urandom, that also fixes it. But I think we
> can workaround this more "generally" by doing the workaround suggested in the
> Jetty issue (pass java.util.Random not java.security.SecureRandom).
> However, it's still not clear how widespread / what evns this issue really
> affects (besides mine)...
