Re: [xwiki-devs] CSRF tests taking long

Hi Vincent, I think the problem there is in the initialization of CSRF component, it seeds an instance of SecureRandom, which in turn takes the randomness from /dev/random AFAIK, and that can be very slow on some hardware. On my laptop the tests take 2:30 if I do not touch the mouse and keyboard during the test run and 1 second if I do. There is an command line option -Djava.security.egd=file:/dev/./urandom (note the /./ part, see http://bugs.sun.com/view_bug.do?bug_id=6202721) that makes Java use /dev/urandom instead, which is less secure, but much faster, we could use it for tests, WDYT?
