[2021-10-19T23:28:44.021Z] -----------------------------

Start with the linked test output and the LIBPATH RtfChild testcase, then inspect RtfChild.java at lines 41 and 60 to understand the AWT failure on Alpine Linux. Determine the expected handling for this headless environment and confirm the result by rerunning the affected test suite.
