Claus Ibsen commented on CAMEL-4235:
------------------------------------
The work around is to use <bean> for error handlers, eg
{code:xml}
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";>
<bean id="dlc" class="org.apache.camel.builder.DeadLetterChannelBuilder">
<property name="deadLetterUri" value="mock:dead"/>
</bean>
<camelContext xmlns="http://camel.apache.org/schema/blueprint";>
<!--<errorHandler id="dlc" deadLetterUri="mock:dead"
type="DeadLetterChannel"/>-->
<route errorHandlerRef="dlc">
<from uri="direct:start"/>
<to uri="mock:result"/>
</route>
</camelContext>
</blueprint>
{code}
> CamelBlueprint2Test testErrorHandler test is failed.
