It seems that after the fix "(CRobotKeyCodeMapping *) sharedInstance"
returns the new object per invocation, so it is not really
sharedInstance. I am not sure I understand what is wrong in the current
code, from the my point of view this is a correct singleton. It it true
that the problem is in access to broken "instance" and not to
"javaToMacKeyMap" inside the "instance"? If not then "javaToMacKeyMap"
should be changed to "self.javaToMacKeyMap".
Do you have a test case to reproduce the bug?
