<AWT Dev> Extra KeyEvents while working via VNC

[Konstantin Bulenkov]

Hello everyone,

 

I’ve faced a weird bug in 1.8.x If I connect from my Mac to another Mac (Finder -> Command+K -> vnc://ip) and trying to send double Command (press, release, press, release) to a Java application (IntelliJ IDEA in my case) then I receive the following:

 

java.awt.event.KeyEvent[KEY_PRESSED,keyCode=157,keyText=⌘,keyChar=Undefined keyChar,modifiers=⌘,extModifiers=⌘,keyLocation=KEY_LOCATION_STANDARD,rawCode=0,primaryLevelUnicode=0,scancode=0,extendedKeyCode=0x9d] on frame0

 

java.awt.event.KeyEvent[KEY_PRESSED,keyCode=0,keyText=Unknown keyCode: 0x0,keyChar=Undefined keyChar,modifiers=⌘,extModifiers=⌘,keyLocation=KEY_LOCATION_UNKNOWN,rawCode=0,primaryLevelUnicode=0,scancode=0,extendedKeyCode=0x0] on frame0

 

java.awt.event.KeyEvent[KEY_RELEASED,keyCode=157,keyText=⌘,keyChar=Undefined keyChar,keyLocation=KEY_LOCATION_STANDARD,rawCode=0,primaryLevelUnicode=0,scancode=0,extendedKeyCode=0x9d] on frame0

 

java.awt.event.KeyEvent[KEY_PRESSED,keyCode=0,keyText=Unknown keyCode: 0x0,keyChar=Undefined keyChar,keyLocation=KEY_LOCATION_UNKNOWN,rawCode=0,primaryLevelUnicode=0,scancode=0,extendedKeyCode=0x0] on frame0

 

java.awt.event.KeyEvent[KEY_PRESSED,keyCode=157,keyText=⌘,keyChar=Undefined keyChar,modifiers=⌘,extModifiers=⌘,keyLocation=KEY_LOCATION_STANDARD,rawCode=0,primaryLevelUnicode=0,scancode=0,extendedKeyCode=0x9d] on frame0

 

java.awt.event.KeyEvent[KEY_PRESSED,keyCode=0,keyText=Unknown keyCode: 0x0,keyChar=Undefined keyChar,modifiers=⌘,extModifiers=⌘,keyLocation=KEY_LOCATION_UNKNOWN,rawCode=0,primaryLevelUnicode=0,scancode=0,extendedKeyCode=0x0] on frame0

 

java.awt.event.KeyEvent[KEY_RELEASED,keyCode=157,keyText=⌘,keyChar=Undefined keyChar,keyLocation=KEY_LOCATION_STANDARD,rawCode=0,primaryLevelUnicode=0,scancode=0,extendedKeyCode=0x9d] on frame0

 

java.awt.event.KeyEvent[KEY_PRESSED,keyCode=0,keyText=Unknown keyCode: 0x0,keyChar=Undefined keyChar,keyLocation=KEY_LOCATION_UNKNOWN,rawCode=0,primaryLevelUnicode=0,scancode=0,extendedKeyCode=0x0] on frame0

 

So, after every Command event I receive a key event with keyCode=0. Apple JRE works fine and doesn’t have such null events. Is this a bug in JRE implementation or should I filter such events by myself?
