public final class SequenceGapException
extends weblogic.jms.common.JMSException

This exception is thrown when a multicast consumer detects a sequence gap in the data stream.

A sequence gap occurs when messages are received out of order, resulting in one or more messages being skipped. If a skipped message is subsequently delivered, it will be discarded.
