I'm using Eclipse Luna with    JBoss Developer Studio (Core Features)    8.0.2.GA-v20150114-2029-B382 and JBoss Fuse Tooling Apache Camel Editor    7.3.0.v20141209-1819-H340-Beta2 

It appears when I open some Camel route.xml files, the file is transformed, and the route is then changed.

For example, I edit a route.xml file like this:

<?xml version="1.0" encoding="ASCII"?>

<!--  to uri="log:src.com.agcs.bih?showAll=true" / --><routes xmlns="http://camel.apache.org/schema/spring">

  <route id="SrcOutTranslatorRoute">

    <from uri="switchyard://TranslateMessageService"/>

    <!--  Exception flow  -->

    <onException>

      <exception>org.apache.camel.ValidationException</exception>

      <exception>javax.xml.transform.TransformerException</exception>

      <handled>

        <constant>true</constant>

      </handled>

      <log message="Error ${exception.class.simpleName}" loggingLevel="ERROR" logName="Bih.SrcDestFlow"/>

      <process ref="BihExceptionHandler"/>

      <to uri="jms:queue:Src.in?connectionFactory=%23ConnectionFactory&amp;transacted=true"/>

    </onException>

    <!--  Normal flow  -->

   <to uri="validator:xml/SrcOutMessage.xsd?useDom=true"/>

    <to uri="xslt:xml/SrcToIdm.xslt"/>

    <to uri="jms:queue:Src.Idm.out?connectionFactory=%23ConnectionFactory&amp;transacted=true"/>

  </route>

</routes>

I save it, and reopen it in the Fuse tooling routes editor. It then gets transformed to this:

<?xml version="1.0" encoding="ASCII"?>

<!--  to uri="log:src.com.agcs.bih?showAll=true" / --><!--  Exception flow  --><!--  Normal flow  --><routes xmlns="http://camel.apache.org/schema/spring">

  <route id="SrcOutTranslatorRoute">

    <from uri="switchyard://TranslateMessageService"/>

    <onException>

      <exception>org.apache.camel.ValidationException</exception>

      <exception>javax.xml.transform.TransformerException</exception>

      <handled>

        <constant>true</constant>

      </handled>

      <log message="Error ${exception.class.simpleName}" loggingLevel="ERROR" logName="Bih.SrcDestFlow"/>

      <process ref="BihExceptionHandler"/>

      <to uri="jms:queue:Src.in?connectionFactory=%23ConnectionFactory&amp;transacted=true"/>

      <to uri="validator:xml/SrcOutMessage.xsd?useDom=true"/>

      <to uri="xslt:xml/SrcToIdm.xslt"/>

      <to uri="jms:queue:Src.Idm.out?connectionFactory=%23ConnectionFactory&amp;transacted=true"/>

    </onException>

  </route>

</routes>

Notice how suddenly the code after the onException has been integrated into onException ?
