Description

I'm using JAXB format for unmarshaling. It is defined like this:

<dataFormats>
<jaxb id="kofax" contextPath="com.indracompany.telefonica.assignmanager"
schema="classpath:DocumentsDataForAssignManager.xsd"/>
</dataFormats>

And used in route like this:

<unmarshal ref="kofax"/>

Sometimes however I get following exception:

org.xml.sax.SAXException: FWK005 parse may not be called while parsing.
at com.sun.org.apache.xerces.internal.jaxp.validation.Util.toSAXException(Util.java:65) ~[na:1.7.0_21]

at org.apache.camel.processor.UnmarshalProcessor.process(UnmarshalProcessor.java:57) ~[camel-core-2.11.1.jar:2.11.1]

Seems that the problem is same as in CAMEL-1565. That ticket was however related to <validate> element.

Right now I have disabled validation on the jaxb format used for unmarshalling and put extra <validate> in the route. It would be however fine to have this issue fixed as well.
