This is a new native method (actually moved from another class) in
JavaFX 21. This is very likely due to a mismatch between the native
library and the Java classes. I suspect you have a directory in your
PATH that is picking up an old javafx_font.dll library. Run your
program with "-Djavafx.verbose=true" to see where the library is
loaded from.<br>
