Line 222227 in build-benchmark.xml is

    <script language="javascript"><![CDATA[

Comments
Note: ant <script> task is broken with modular jdk9 due to a known ant issue: https://bz.apache.org/bugzilla/show_bug.cgi?id=58271 This issue is due to change in behaviour of ClassLoader.getResource for resources in named modules.
