Description Nicolas Bros CLA 2011-05-24 05:44:21 EDT 
I get the following NoSuchMethodError when trying to run the API analysis.
But I don't understand how a NoSuchMethodError is possible here, because the caller and callee seem to be both in the same plug-in (jdt.core).

Please disregard this bug : I didn't realize I was mixing 2 different installations of Eclipse.
