ADDITIONAL SYSTEM INFORMATION :
OSX/ Java build 14+36

A DESCRIPTION OF THE PROBLEM :
The file associations command in jpackage (--file-associations) does not seem to function when creating packages for OSX. (though it works for Windows and Linux)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Create a basic app with a main method that can output args passed in
2) Build the app and package it using jpackage, using the --file-associations to associate it with a filetype
3) Install the app
4) Create a file of the type that is associated with your app
5) Double click the file

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The app will be opened, with the file's path passed as an element of the argument array to the main() method.
ACTUAL -
The app is opened, but the arguments are empty.

---------- BEGIN SOURCE ----------
Any app with a main method that can output its arguments.
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
None that I have found yet.

FREQUENCY : always
