Issue

Using jBPM 3.2 in SOA-P 5.0.2.GA, we encountered a NullPointerException while sending email on the task that has notify="true" attribute:

java.lang.NullPointerException
        at org.jbpm.mail.Mail.send(Mail.java:132)
        at org.jbpm.mail.Mail.execute(Mail.java:73)
        at org.jbpm.graph.def.Action.execute(Action.java:137)
        at org.jbpm.graph.def.GraphElement.executeAction(GraphElement.java:280)
        at org.jbpm.graph.def.GraphElement.executeActions(GraphElement.java:237)
        at org.jbpm.graph.def.GraphElement.fireAndPropagateEvent(GraphElement.java:207)
        at org.jbpm.graph.def.GraphElement.fireEvent(GraphElement.java:190)

We have customized the jbpm.mail.templates.xml file to meet our business requirements.
