The error output observed is
java.lang.Exception: FAILED: getMaxAdvance is not max for font: java.awt.Font[family=L M Math Italic5,name=L M Math Italic5 Bold,style=bolditalic,size=10] getMaxAdvance(): 14 getWidths()[77]: 15

Comments
Closing this one as duplicate of JDK-8221305. The test was retired and for JDK15 the spec was amended with JDK-8230672. Will take care of backporting JDK-8221305 so as to remove the test from 11u.
