Comment 1 Olivier Thomann CLA 2004-08-19 14:27:12 EDT 
getKey() should not be an infinite loop.
Comment 2 Olivier Thomann CLA 2004-08-19 15:39:48 EDT 
I changed the getKey() of a type variable not to recursively call the getKey of
the  declaring element. I simply add the name of the declaring element instead.
I will review this with Jim when he is back from vacations.
Fixed and released in HEAD.
Regression test added.
