A white screen of death appears when running the generator job, displaying URL like ${JENKINS_URL}/job/${JOB_NAME}/build?delay=0sec.

Nevertheless, generation job executes successfully, generated jobs appear / disappear as expected after build, and after refreshing the page Jenkins displays generator job page again.

All other builds, both parametrized and not-parametrized are triggered as expected, without blank screen.

Both system log and jenkins.log files display no errors or exceptions:
