scb, #218:
Fixed the problem with removing the method from the runtime, even when it is preserved. The current fix still leaves an interval, where the behavior is not accessible, but the fix is confined to saveSource. A more elaborate solution would be to always ignore cleanups in ClassElemFragment nodes, and once there is a negative decision, to remove the behavior then.
