ADDITIONAL SYSTEM INFORMATION :
Mac OS Big Sur/ Java Open JDK 17

A DESCRIPTION OF THE PROBLEM :
Our application has an action triggered using the Control-Space keyboard shortcut on Mac OS. Unfortunately with newer Java versions like 17, triggering the shortcut no longer calls the action.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the code below which adds a key listener on a JTextArea and list all key pressed events, the Ctrl-Space shortcut does not trigger a specific event. With Java 8 this event is received:

KP java.awt.event.KeyEvent[KEY_PRESSED,keyCode=32,keyText=␣,keyChar='',modifiers=⌃,extModifiers=⌃,keyLocation=KEY_LOCATION_STANDARD,rawCode=0,primaryLevelUnicode=0,scancode=0,extendedKeyCode=0x0]

but with Java 17 the key pressed event containing the space key and the ctrl modifier is no longer received.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The Ctrl-Space keys combination should trigger a key pressed event in the key listener.
ACTUAL -
The Ctrl-Space keys combination does not trigger a key pressed event in the key listener.
