Subject [jira] Created: (CAMEL-795) MinaConsumerTest failure
Date Fri, 08 Aug 2008 05:50:52 GMT
MinaConsumerTest failure
------------------------

                 Key: CAMEL-795
                 URL: https://issues.apache.org/activemq/browse/CAMEL-795
             Project: Apache Camel
          Issue Type: Bug
          Components: camel-mina
    Affects Versions: 1.4.0
            Reporter: Hadrian Zbarcea
            Assignee: Hadrian Zbarcea
             Fix For: 1.5.0


The test fails with the following error:

junit.framework.ComparisonFailure: expected:<[Bye World]> but was:<[]>
	at junit.framework.Assert.assertEquals(Assert.java:81)
	at junit.framework.Assert.assertEquals(Assert.java:87)
	at org.apache.camel.component.mina.MinaConsumerTest.testSendTextlineSyncText(MinaConsumerTest.java:28)
...

One test sends sync the text "World" and the should receive "Bye World" in response.
2008-08-08 01:35:25,589 DEBUG MinaProducer - Message received: Bye World 
2008-08-08 01:35:25,589 DEBUG MinaProducer - Message received:  
2008-08-08 01:35:25,589 DEBUG MinaProducer - Message received: Bye  
2008-08-08 01:35:25,589 DEBUG MinaProducer - Message received:  

There are actually not one, but two messages received which causes the reply to be overridden
by the second message.  The problem is with the test itself that actually returns "Bye " +
body + "\n"!  Because the test uses the 'textline' mina codec, the encoder actually adds another
'\n'.  With the textline codec there's one message per line, so the extra \n makes it two
lines and hence the extra message.  The decoder at the other end suppresses the LineDelimiter
(\n), so the extra message is actually an empty string.

Removing the extra \n in the message fixes the test, but the notes above should be considered
when camel-mina is used with the textline codec.
