-----------------------------------------------------------
It works if using <redeliveryPolicyProfile> tag instead:
{code}
...
<camelContext id="redeliveryTestContext" trace="true"
xmlns="http://camel.apache.org/schema/blueprint"; >
<redeliveryPolicyProfile id="myRedelivery"
delayPattern="{{delayPattern}}"
maximumRedeliveries="{{maxDeliveries}}"
retryAttemptedLogLevel="WARN" logRetryAttempted="true" />
<onException useOriginalMessage="false"
redeliveryPolicyRef="myRedelivery">
<exception>java.lang.IllegalStateException</exception>
<handled>
<constant>true</constant>
</handled>
<to uri="log:org.apache.camel.test?level=DEBUG" />
</onException>
<route id="startExceptionTest">
<from uri="timer://foo?repeatCount=1" />
...
{code}
But we need to fix the delayPattern with property placeholder in
<redeliveryPolicy> tag.
