the class ConnIdUtil method processIcfException.
/**
* Transform ConnId exception to something more usable.
*
* ICF throws exceptions that contains inner exceptions that cannot be
* reached by current classloader. Such inner exceptions may cause a lot
* of problems in upper layers, such as attempt to serialize/deserialize
* them. Therefore we cannot pass such exceptions to the upper layers.
* As Throwable is immutable and there is no good way how to copy it, we
* just cannot remove the "bad" exceptions from the inner exception stack.
* We need to do the brutal thing: remove all the ICF exceptions and do
* not pass then to upper layers. Try to save at least some information
* and "compress" the class names and messages of the inner ICF exceptions.
* The full exception with a stack trace is logged here, so the details are
* still in the log.
*
* WARNING: This is black magic. Really. Blame Sun Identity Connector
* Framework interface design.
*
* @param connIdException
* exception from the ConnId
* @param connIdResult
* OperationResult to record failure
* @return reasonable midPoint exception
