the class ContentEnricherTests method replyChannelReplyTimingOut.

/**
 * In this test a {@link Target} message is passed into a {@link ContentEnricher}.
 * The Enricher passes the message to a "request-channel" that is backed by a
 * {@link QueueChannel}. The consumer of the "request-channel" takes a long
 * time to execute, longer actually than the specified "replyTimeout" set on
 * the {@link ContentEnricher}.
 *
 * Due to the occurring replyTimeout, a Null replyMessage is returned and because
 * "requiresReply" is set to "true" on the {@link ContentEnricher}, a
 * {@link ReplyRequiredException} is raised.
