Example 2 with ErrorMapping

use of org.mule.runtime.core.internal.exception.ErrorMapping 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
 * an exception in the causes that match with an Known error type then this method will try to find the error that the current
 * {@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
 *
 * @return a {@link MessagingException} with the proper {@link Error} associated to it's {@link CoreEvent}
