Hi Sergey,
It seems the hidpi issue of the test is because of JDK-8178025
<https://bugs.openjdk.java.net/browse/JDK-8178025> where we calculate
the fontmetrics because of scaleChange
/jdk10-b33/bin/java JEditorPaneLayoutTest
Exception in thread "main" java.lang.RuntimeException: Wrong size
java.awt.Dimension[width=180,height=10] expected
java.awt.Dimension[width=180,height=44]
at JEditorPaneLayoutTest.main(JEditorPaneLayoutTest.java:87)
jdk10-b34/bin/java JEditorPaneLayoutTest
Exception in thread "main" java.lang.RuntimeException: Wrong size
java.awt.Dimension[width=181,height=10] expected
java.awt.Dimension[width=180,height=44]
at JEditorPaneLayoutTest.main(JEditorPaneLayoutTest.java:87)
Since all the regression tests for this issue like
javax/swing/plaf/basic/BasicTextUI/8001470/bug8001470.java,
javax/swing/JTextArea/ScrollbarFlicker/ScrollFlickerTest.java and the
present test
is passing with the fix and I have already created a JBS
issueJDK-8229222 <https://bugs.openjdk.java.net/browse/JDK-8229222>to
work on the test issue, which is not directly related to this fix, can
we check this in and I work on the JBS issue subsequently?
Regards
Prasanta

Hi, Prasanta.
I have one additional suggestion. I think we need to check the whole
related sequence of bugs
0) JDK-8001470 - The bug which is unrela6ed to the current bug, but it
is introduce the test from which we start the step (1)
1) Initial bug was reproduced on Solaris 11 only:
https://bugs.openjdk.java.net/browse/JDK-8130892
As a fix the check for "uninitialized" state was changed, but it was
caused next regression
2) https://bugs.openjdk.java.net/browse/JDK-8160246 , it also
reproduced only on Solaris and this is the fix where we added the
"rootViewInitialised" flag, but it cause next regression
2) Current bug https://bugs.openjdk.java.net/browse/JDK-8226513
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 :
https://bugs.openjdk.java.net/browse/JDK-8130892?focusedCommentId=13822701&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13822701
I doubt that negative size is a correct value for the component.

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 "problem" was there even before the fix, for example
with jdk13 (fails with jdk11, jdk12 too )

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.
