BadURIException on analysis job as RefactorerImpl.kReSCoreOperation

When running an analysis job it seems that sometimes some data are not formally correct, and raise BadURIException. This causes the entire analysis job to fail. From the stack-trace I don't clearly understand if the bad URI is fed by the Refactorer or not.

I agree with the proposal of Andrea Giovanni Nuzzolese, i.e. that "in such a situation the Refactor should not break the execution, even if it is not possible to resolve the bad URI."

Stack-trace:
