Hi Patrick,
that is possible in the RIFE version of continuations. While
stripping it out you seem to have removed the feature. Line 140 of
ContinuationManager reads "if (true)", while in the RIFE version this
checks for a setting that indicates if the cloning should happen or not.
One thing that also really helps to work around these errors, is to
simply extract the piece of logic that contains unclonable variables
into a dedicated method. It will then not be instrumented.
Hope this helps,
Geert
