Comment 1 Philipe Mulet CLA 2004-12-02 19:28:01 EST 
Seems like a method with no return type...
Comment 2 Jerome Lanneluc CLA 2004-12-08 10:17:28 EST 
Could not reproduce. Added null check in MethodBinding#signature() and
genericSignature()
Comment 3 Frederic Fusier CLA 2004-12-15 07:33:16 EST 
Verified added code for 3.1 M4 using build I200412142000.
