Pay attention to the e's, for example:

Amazon Corretto 8: wrong rendering for font size less than 101 and other wrong rendering for font size greater than 100
java-8_font_with_contextual_alternates_not_correct_rendering_below_font_size_100

Amazon Corretto 11-16, 19: wrong rendering for font size less than 101 and correct rendering for font size greater than 100
java-19_font_with_contextual_alternates_not_correct_rendering_below_font_size_100

It would be great if this could be fixed for OpenJDK (for all sizes).

Workaround for font size less than 101:

Font font = new Font(fontName, Font.PLAIN, 100);
Map map = new HashMap();
map.put(TextAttribute.LIGATURES, TextAttribute.LIGATURES_ON);
font = font.deriveFont(map);
