[jbpm-issues] [JBoss JIRA] Resolved: (JBPM-2487) Bug in GroupActivity.execute(ExecutionImpl execution)

Bug in GroupActivity.execute(ExecutionImpl execution) ----------------------------------------------------- Key: JBPM-2487 URL: https://jira.jboss.org/jira/browse/JBPM-2487 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.0 Reporter: Michael Wohlfart Assignee: Tom Baeyens Priority: Minor Fix For: jBPM 4.2 Attachments: ForkGroupReverseTest.java, process.jpdl.xml Original Estimate: 4 hours Remaining Estimate: 4 hours just browsing through the codebase and trying to understand the magic, I came across this in line 56 of GroupActivity.java: ExecutionImpl concurrentRoot = null; if (Execution.STATE_ACTIVE_ROOT.equals(execution.getState())) { concurrentRoot = execution; } else if (Execution.STATE_ACTIVE_ROOT.equals(execution.getState())) { concurrentRoot = execution.getParent(); } else { throw new JbpmException("illegal state"); } I assume getState() doesn't have any side effects, so I guess this is a bug
