Based on the analysis and test runs, I have added a null check to return null when _ImageIcon_ is null and added to the map. The test is made as headful since the occurrence of issue seems to be dependent on machine and is unpredictable. Headful test didn't cause any issue after multiple runs and iterations. ------------- PR: https://git.openjdk.org/jdk/pull/11104
