RFR: JDK-8236544: Confusing javac message: return type of accessor method abc() is not compatible with type of record component number

[Vicente Romero]

Hi,

Please review this very simple change to an error message related to 
records. The patch makes the error message more specific as the spec 
doesn't allow an accessor method to declare a return type other than the 
same declared by the corresponding record component. The current error 
message is referring to compatibility between types instead of exact 
match which is what the spec allows,

Thanks,
Vicente
