Are you crazy? Are you really crazy? You let an essential Keyboard-Bug 1 year untouched?!
Whats going on at Oracle?!
I've written a lot of Java Apps for MacOS, and they will become unusable with MacOS Sierra. The bug reports are over 1 year old... nothing happen!
If a customer is pressing one key longer than 2 seconds... the complete Keybaord Input System will block any keyboard inputs.
What the hell^^
Copy the Keylistener code from JDK 7 into JDK 8 and 9 and this will be fixed in 10 seconds^^
Im angry, very angry with so much ignorance!
