A DESCRIPTION OF THE PROBLEM :
I have a large JTable (500 rows by 25 columns) located inside a JScrollPane. When I scroll the table using the vertical scroll bar random rows do not completely repaint. I tried commenting out all my code that updates the cells giving me a blank table and the problem still occurs.
I found that if I select a row the problem goes away. I can select the row with the mouse or programmatically. If I select a row programmatically and clear the selection then the problem returns.
I have found that if I switch to JDK 8 I do not see the problem at all.

REGRESSION : Last worked in version 8u311


CUSTOMER SUBMITTED WORKAROUND :
Always have a row selected.

FREQUENCY : always
