Hi, i was trying to use the @stevel05 RichViewfx CodeArea control and can't make it work on release mode.

The behavior it's a quite strange as in release mode the app crashes showing this log:

I currently looking for a code editor for my DSL, any B4J idea?

Try this:
B4X:
#VirtualMachineArgs: --add-opens javafx.graphics/javafx.scene.text=ALL-UNNAMED
#PackagerProperty: VMArgs = --add-opens javafx.graphics/javafx.scene.text=b4j
😲

I (we) need some explanation/tutorial/documentation about those things.

Experimentation and investigation shows that an export is required as well.

This works for me:

B4X:
#VirtualMachineArgs: --add-opens javafx.graphics/javafx.scene.text=ALL-UNNAMED  --add-exports javafx.graphics/com.sun.javafx.text=ALL-UNNAMED
#PackagerProperty: VMArgs = --add-opens javafx.graphics/javafx.scene.text=b4j --add-exports javafx.graphics/com.sun.javafx.text=b4j

Note this is for java > 8 only, so I won't be adding it to the released library demo for now.

No, I didn't try that. It's been a long time since I looked at it at all.
