When a method changes out from under your feet in the Debugger (e.g., you remove an instvar triggering a recompile of a method through which you've stepped), the Debugger blanks out contents. In the UI, this manifests as a blank code pane.
This change resets the contents ivar by setting it to the new, recompiled, CompiledMethod as a side effect of calling self selectedMessage.
