How add OpenJavafx 11 GUI components on SWT part using OpenJDK 11 and Eclipse photon 2018-12 - swt

Question

I am using OpenJDK 11 + OpenJavafx 11 environment in Eclipse Photon 2018-12 and created one plugin GUI project in eclipse. My aim is to add the OpenJavafx components(Button) on SWT Part.
These are steps I am following to render the javafx Button on top of SWT Part
Application e4xmi view:
There are two plugins using
1. com.rcp.main – Main RCP Application, there are two parts on part stack in main plugin.
Part 1 (Sample Part 1 : class URI bundleclass://com.rcp.main/com.rcp.main.parts.SamplePart) Rendered with pure SWT created from eclipse template figure below. It is working as expected.
Part 2 (Sample Part 2: class URI bundleclass://com.rcp.main/com.rcp.main.parts.SamplePart1) Rendered with open Javafx GUI components (Button) on SWT part. I am getting empty one exception from as figure below
2. com.rcp.feature – This feature included plugins with com.rcp.main and org.eclipse.fx.osgi
