[jbpm-issues] [JBoss JIRA] Commented: (JBPM-2758) NPE on assignmenthandler when using fork/join

[Ronald van Kuijk (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBPM-2758?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12507063#action_12507063 ] 

Ronald van Kuijk commented on JBPM-2758:
----------------------------------------

The reason is that the processdefinition is null in the execution where the assignmenthandler for the task after the join is initialized in ExecutionImpl. The processinstance id is not null, so adding an additional 'getProcessDefinition()' only when the definition is null solves the issue. Might need additional investigation why it is null, but the fix can be included I think.
