PhaseInterceptorChain Interceptor for {service} has thrown exception, unwinding now java.lang.NullPointerException

[Muhammad Ali]

Hello,

I am using windows 10, ServiceMix 7.0.1 and Java version 1.7.0_80.

If the maximumRedeliveries count in the below code is greather than 1. I am
getting below mentioned exception. Why I can not set the maximumRedeliveries
greather than 1. Any help would be highly appreciated.

<camel:onException id="onConnectException">
<camel:exception>java.net.ConnectException</camel:exception>
<redeliveryPolicy *maximumRedeliveries="2"* redeliveryDelay="1000"
logRetryAttempted="true" retryAttemptedLogLevel="DEBUG" />
<!-- Define that handling is needed -->
<camel:handled>
<camel:constant>true</camel:constant>
</camel:handled>
<camel:to uri="direct:commonExceptionHandler"/>
<camel:convertBodyTo type="org.w3c.dom.Document" />
<camel:to uri="log:onConnectException?le
vel=ERROR&amp;multiline=true&amp;showBody=true&amp;showProperties=true" />
</camel:onException>
