Strangely, setting stdin to /dev/null and stderr to /dev/null makes no difference in the test results. stdout is the Jenkins pipe, which is Java of course, but roughly a popen(x, "r"). I have no explanation at this point why specific tests fail - other than OpenSSH, which I know attempts to prompt if it thinks the tty is even remotely reasonable.
