Hi Vincent,

As of JDK 9 the Standard Extension mechanism, as implemented by the 
"lib/ext" directory in the JDK, has been removed. If you need to locally 
modify a class in one of the javafx.* modules you will either need to 
build JavaFX from source or patch the module (presumably, using the "--patch-module" option of "java".
