      testJob:

      
<job id="testJob" xmlns="http://xmlns.jcp.org/xml/ns/javaee" version="1.0">
	<flow id="test">
		<step id="step1" next="step2">
			<batchlet ref="storesPersistentDataBatchlet" />
		</step>
		<step id="step2" >
			<batchlet ref="testBatchlet">
				<properties>
					<property name="fromStep" value="step1" />
					<property name="throwException" value="#{jobParameters['throwException']}" />
				</properties>
			</batchlet>
		</step>
	</flow>
</job>

      step1: stores persistent user data
      step2: reads persistent user data from step1

      To create a test constellation for a job restart step2 can forced to throw an exception.

      Steps to reproduce:

      • start Wildfly
      • start testJob with parameter throwException = "true"
      • stop Wildfly
      • start Wildfly again
      • restart testJob with parameter throwException = "false"

      then we get:

      We use persistent user data to provide information from one step to a following step. This works fine, except during restarting the job after a restart of the Wildfly.

      When we get a ClassNotFoundException concerning our persistent user data class.
