It looks fine, thank you for clarification.

Can you please file a separate CR to check the negative bounds, such bounds do 
not look correct.

Hi Sergey,

Any more feedback on this? It seems it comes out negative if frame.pack() is 
called after frame.setVisible() in linux which is the testcase for 8001470.

Hi Sergey,

When frame.setVisible() is called we do

Frame.setVisible() -> BorderLayout.layoutContainer() where we do
if ((c=getChild(CENTER,ltr)) != null) {
            c.setBounds(left, top, right - left, bottom - top);
        }

Now, in linux we get
bottom = target.height - insets.bottom; 0-5=-5
and right = target.width - insets.right; 0-5=-5

right=-5, left=5, bottom=-5,top=25

so component's or JRootPane's bounds width=-10,height=-30

Now, when we call frame.pack(), we do GridLayout.preferredLayoutSize() where 
Component comp = parent.getComponent(i) returns JTextField as component with 
-10x-15 as width,height

as I saw that Dimension d returns negative width(-10) and height (-15) in 
JEditorPane.getPreferredSize() when bug8001470.java is run on linux.

But why this size is negative?


The "rootViewNeedsLayout" flag causes this check to be not used and still pass 
and I think this is needed.


Also, as told, the hidpi issue of the present test is caused by 8178025
<https://bugs.openjdk.java.net/browse/JDK-8178025>and should need some 
SwingUtilities2.isScaleChanged check somewhere, which I intend to work on in 8229222 
<https://bugs.openjdk.java.net/browse/JDK-8229222>, if you do not have any objection.

Hi, Prasanta.

Since this is the second regression of JDK-8130892, my suggestion was to try to 
revert all of these fixes and check that such changes are really necessary. Do 
we really need to change the check from
"d.width <= 0 || d.height <= 0" to "d.width <= 0 || d.height <= 0", and do wee 
need a flag?

I do not suggest to re-implement the fix, but recheck that we will not 
integrate on more regression.

    And you already found by the test that it dose not take into account the 
fact that the GConfig may be different when you calculate the size for 
invisible component, and the size after it is became visible, probably ithe fix 
itself does not take into account this?

    It is also quite interesting to check the root cause of the JDK-8130892 :

        Yes, it is. I have modified the jtreg command line to test in uiScale 
1. It now pass in windows and others and fails without the fix.

                But I also see that the failure is not because of the fix. The

                So, the 1 pixel difference in width was there even before this 
fix and also this fix fixes the height of the basic text component and the unit 
tests of JBS works ok, so to me this fix looks ok to me.

                +1 for the fix from me and

                I have added the test to problem list only for windows to 
figure out the 1 pixel difference in width which seems to be because of 
layouting in windows.
