<Swing Dev> RFR: PIT Bug 8167988 : java.nio.file.InvalidPathException if click button in JFileChooser demo of SwingSet2

[Phil Race]

SQE reports some 35 tests fail as a result of this bug.
I am backing out the change that caused it from our PIT and need a reviewer.
SQE will verify this before I push.
