Description Stephan Herrmann CLA 2011-04-21 13:19:34 EDT 
A synthetic access method (e.g., for this$0) will be generated with
wrong signature if tsuper role is read from .class file.

This manifests in a method signature with a role interface parameter,
but inside the method, this argument is treated as the role class.

Observed in OTSample-FlightBonus when only touching/saving role file
GUIConnector/FlightBonusDialog.

test & proposed fix

The problem is rooted in the fact that copy inheritance triggers
(via resolveGeneratedMethod -> resolveTypesFor) wrapping of types in the
method signature even for copies of synthetic methods.

Solved by passing one more flag into resolveTypesFor.

Test results pending.
