A DESCRIPTION OF THE PROBLEM :
The following tests
  java/awt/event/MouseWheelEvent/InfiniteRecursion/InfiniteRecursion_1.java
  java/awt/event/MouseWheelEvent/InfiniteRecursion/InfiniteRecursion_2.html
  java/awt/event/MouseWheelEvent/InfiniteRecursion/InfiniteRecursion_3.html
  java/awt/event/MouseWheelEvent/InfiniteRecursion/InfiniteRecursion_4.java
  java/awt/event/MouseWheelEvent/InfiniteRecursion/InfiniteRecursion.java
fail on Windows and MacOS because expected and actual event counts are different
The issue was not observed on Linux

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
$ ./r.sh C\:/Program\ Files/Java/jdk-10.0.1/ "-Djava.awt.headless" test/java/awt/event/MouseWheelEvent/InfiniteRecursion
