Example 2 with ConnectionBrokenException

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
