Error in lambda expression does not appear directly in code.

Hello,

When I delete a parameter in setOnMouseEntered at javafx.scene.shape.Path, it displays an error.

Same as the file.

Even after startup.

However, if I delete a parameter in setOnFinished at javafx.animation.FadeTransition, it will display an error in the file even after it is run, but not in the code.

Please repair.

Thank you
