The test requires clean-up there are couple of commented lines.
JBS issue does not seem to be linked, can you check by adding.
`/issue add 8235404`
Test summary in jtreg needs an update

test/jdk/javax/swing/JOptionPane/OptionPaneInput.java line 86:

The JOptionPane can be add as a split window using PassFailJFrame.splitUI() since currently it gets blocked by the testUI.

test/jdk/javax/swing/JOptionPane/OptionPaneInput.java line 89:

Since parentComponent of JOptionPane is null running into NPE.


        parentComponent.revalidate();
        parentComponent.repaint();
