Describe the bug

A clear and concise description of what the bug is.
I am unable to draw text using TextLayout after upgrading from sun/oracle jdk1.8 to corretto 8( jdk8.202.08.2_64bit and jdk8.212.04.2_64bit)

To Reproduce

Steps and (source) code to reproduce the behavior:-
My app uses activiti, which calls java awt classes to draw its bpmn modelling diagram.
Initially I was getting following NPE :
java.lang.NullPointerException
sun.awt.FontConfiguration.getVersion(FontConfiguration.java:1264)
sun.awt.FontConfiguration.readFontConfigFile(FontConfiguration.java:219)
sun.awt.FontConfiguration.init(FontConfiguration.java:107)
sun.awt.X11FontManager.createFontConfiguration(X11FontManager.java:774)
sun.font.SunFontManager$2.run(SunFontManager.java:431)

Then I figured out it was the missing font libraries.

Just for the sake of investigation, I created my own fontconfig.properties in corretto jre/lib

I also find the fontmanager rpm package, needed by fontconfig, is also installed in my servers:
rpm -qa |grep -i font
fontconfig-2.10.95-10.el7.x86_64
fontpackages-filesystem-1.44-8.el7.noarch

And I copied the following fonts from jdk1.8/jre/lib to corretto jre/lib:
LucidaSansDemiBold.ttf, LucidaBrightDemiBold.ttf, LucidaSansRegular.ttf,LucidaBrightDemiItalic.ttf ,LucidaTypewriterBold.ttf,LucidaBrightItalic.ttf,LucidaTypewriterRegular.ttf,LucidaBrightRegular.ttf
LucidaTypewriterBoldOblique.ttf,LucidaSansDemiOblique.ttf,LucidaTypewriterOblique.ttf,LucidaSansOblique.ttf

Now I see the rectangles and lines in the diagram alright, but the text is not getting displayed.
This is how the awt classes are called to write the text within the rectangles:
AttributedString attributedString = new AttributedString(text);
attributedString.addAttribute(TextAttribute.FONT, g.getFont());
attributedString.addAttribute(TextAttribute.FOREGROUND, Color.black);
AttributedCharacterIterator characterIterator = attributedString.getIterator();
int currentHeight = 0;
List layouts = new ArrayList();
String lastLine = null;
LineBreakMeasurer measurer = new LineBreakMeasurer(characterIterator, g.getFontRenderContext());
TextLayout layout = null;
while (measurer.getPosition() < characterIterator.getEndIndex() && currentHeight <= boxHeight) {
int previousPosition = measurer.getPosition();
layout = measurer.nextLayout(boxWidth);
int height = ((Float)(layout.getDescent() + layout.getAscent() + layout.getLeading())).intValue();

layouts.add(layout);
currentHeight += height;

}
int currentY = y + (centered ? ((boxHeight - currentHeight) /2) : 0);
int currentX = 0;
for(TextLayout textLayout : layouts) {
currentY += textLayout.getAscent();
currentX = x + (centered ? ((boxWidth - ((Double)textLayout.getBounds().getWidth()).intValue()) /2) : 0);
textLayout.draw(g, currentX, currentY);
I see layout.getDescent(), layout.getAscent(), layout.getLeading() are returning huge numbers(always 240 in my case, whereas with oracle java 1.8, these used to be like getDescent()= 2.347168 layout.getAscent()= 10.45752)

Do these not work with corretto 8?
