I have looked at https://docs.oracle.com/javase/tutorial/uiswing/lookandfeel/_nimbusDefaults.html where default color for 
EditorPane.background and TextPane.background is NimbusBlueGrey and not White what we have now, so I think we are having what is being specified in nimbus-default.
SwingSet2 background color for the demos are same before and after the fix.
I am not sure about the difference between background and shape but I have ran full JCK/JTREG tests and all are fine. I also tried passing Nimbus L&F via CI script for JCK/jtreg tests and those are also same before and after fix.
