Camel Transformer using inconsistent sources

I have a simple xml transformer:

<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="

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>

The xslt is very simple then:

<xsl:template match="/">
<afterXlst>
<xsl:value-of select="test:talk/text" />
</afterXlst>
</xsl:template>

With this example run multiple times (3 in the cases below), I'm seeing inconsistent inconsistent transformers being used with 2.10.0.fuse-71-047 and also 2.11 SNAPSHOT:
