https://bugs.openjdk.java.net/browse/JDK-8215117

A latent bug in this test was recently exposed by another change. This 
test keeps its own list of fields that are hidden by reflection, and the 
list was incomplete.  This change updates the list in the test.

I'm hoping this can be considered trivial.
