We discovered the following use of setAccessible in rt/apps/toys that was missed when auditing the use of internal API:

apps/toys/Hello/src/main/java/hello/dialog/wizard/ImplUtils.java:
    Parent::getChildren

Note that there is a bug already filed against rt/apps/experiments to remove use of internal classes and methods, JDK-8158334. Since those programs do not currently compile or run currently, and access other internal API, I just added a note about setAccessible to that bug.
