After FreeType update the ratio of width calculated in this test is "1.3757962" in our Oracle Linux 10 machines and it is rounding off to "1.4" and not the "1.3" value as expected in this test. Taking the average ratio out of both width and height for a larger font will give result in values near to the ideal "1.3" ratio. After making this test more robust it passes on all versions of all platforms in our CI. javax/swing/text/html/CSS/8231286/HtmlFontSizeTest.java update is also included in this PR.

You have the define of FT_CONFIG_OPTION_USE_HARFBUZZ  still commented out (correct)

src/java.desktop/share/native/libfreetype/src/autofit/ft-hb.h line 28:

And this file is only included if it is defined ... so you aren't using it. So this does not add up
