FULL PRODUCT VERSION :
java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Linux alcibiade 4.4.0-57-generic #78-Ubuntu SMP Fri Dec 9 23:50:32 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

EXTRA RELEVANT SYSTEM CONFIGURATION :
French AZERTY keyboard

A DESCRIPTION OF THE PROBLEM :
Dead key (ie. ^ or ��) are not detected with KeyEvent events. Therefore it's impossible to write characters like "^" or "��" or "��".

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Write a simple program which displays the key code (see source code), an hit:

- "^" ;
- "^" + "e".

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
- "^" : code=DEAD_CIRCUMFLEX; text=^
- "^" + "e" : code=UNDEFINED; text=��
ACTUAL -
- "^" : code=UNDEFINED; text=
- "^" + "e" : code=E; text=e

REPRODUCIBILITY :
This bug can be reproduced always.
