use of org.mule.runtime.api.message.ErrorType in project mule by mulesoft.

the class MessagingExceptionResolver method resolve.

/**

 * <p>
 * This method will pick the FIRST cause exception that has a mule or extension KNOWN error as the real cause, if there is not

 * {@link Event} is carrying.
 * <p>
 * When there are multiple exceptions that contains the same root error type, then this method will wrap the one that has
 * highest position in the causes list
