A DESCRIPTION OF THE PROBLEM :
Command line launched is showing a Folder as the icon in the Dock. This is somewhat confusing.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
For early testing of code I command line compile with...

javac -d . --module-path /Users/mjh/Documents/javafx-sdk-19/lib --add-modules javafx.base,javafx.controls BTCMonitor.java

and run with...

java --module-path /Users/mjh/Documents/javafx-sdk-19/lib --add-modules javafx.base,javafx.controls us.hall.btc.BTCMonitor

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Some javafx specific icon in the dock to indicate the running application process.
ACTUAL -
A generic Folder icon is shown

FREQUENCY : always
