@HimaBinduMeda There is a minor merge issue that will need to be fixed up following the recent integration of the changes from PR #2047 .

To address this, do the following:

1. Merge in the latest jfx master.
2. Apply the following patch:


--- a/modules/javafx.web/src/main/native/Source/WebCore/platform/graphics/ComplexTextController.cpp
+++ b/modules/javafx.web/src/main/native/Source/WebCore/platform/graphics/ComplexTextController.cpp
@@ -499,7 +499,7 @@ void ComplexTextController::ComplexTextRun::setIsNonMonotonic()
 #else
     for (unsigned i = 0; i < m_glyphCount; ++i) {
         // Skip zero-width glyphs if needed
-        if (m_font.isZeroWidthSpaceGlyph(m_glyphs[i]))
+        if (m_font->isZeroWidthSpaceGlyph(m_glyphs[i]))
             continue;
         // Handle out of bound case
         unsigned charIndex = indexAt(i);



I've already tested it both locally, and in our CI, so I'll just run a sanity test once you update the PR.
