[jira] [Commented] (CAMEL-6020) Camel Transformer using inconsistent sources

["Willem Jiang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-6020?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13566186#comment-13566186 ] 

Willem Jiang commented on CAMEL-6020:
-------------------------------------

The issue is caused by there are bunches of type converter which can turn a byte into a Source. The result could be StreamSource or StaxSource or ByteSource.
Because these converters are loaded in different sequence when camel is loading the converter, so we hit this kind of issue.

To fix the issue, I just changed the type converter calling sequence to make sure we get the exact Source object we want first.

> I have a simple xml transformer:
> {code}
> <camel:camelContext id="camelContext" trace="true">
> <camel:route id="testRoute">
> <camel:from uri="direct:testEndpoint" />
> <camel:process ref="testProcessor" />
> <camel:marshal>
> <camel:jaxb fragment="true" partClass="test.Talk" contextPath="test"
> partNamespace="{http://test/}talk"/>
> </camel:marshal>
> <camel:to uri="log:TEST-AFTER-MARSHALL" />
> <camel:to uri="xslt:xslt/transform.xsl?transformerFactory=saxonTransformerFactory" />
> <camel:to uri="log:TEST-AFTER-XSL" />
> </camel:route>
> </camel:camelContext>
> {code}
> The xslt is very simple then:
> {code}
> <xsl:template match="/">
> <afterXlst>
> <xsl:value-of select="test:talk/text" />
> </afterXlst>
> </xsl:template>
> {code}
> With this example run multiple times (3 in the cases below), I'm seeing inconsistent inconsistent transformers being used with 2.10.3 and also 2.11 SNAPSHOT:
