Asynchronous processing from active business context causes StackOverflowError ------------------------------------------------------------------------------ Key: JBSEAM-4227 URL: https://jira.jboss.org/jira/browse/JBSEAM-4227 Project: Seam Issue Type: Bug Components: Async, BPM Affects Versions: 2.1.2.CR2 Environment: Tomcat 6.0.18 Seam 2.1.2.CR2 download, quartz (also thread local dispatcher doesn't work), JBPM 3.3.x Reporter: Gena Batalski I want to send an asynchronous event from an JBPM handler. The event is scheduled and the taskId and processId are present. Then, when the business context should be restored during the asynchronous event processing (ContextualAsynchronousRequest.setup), Seam tries to resume the task (BusinessProcess.instance().resumeTask(taskId);) and it ends with StackOverflowError. I investigated the problem and found, that in my case the entity manager can not be instantiated. This is the call stack which causes troubles: ContextualAsynchronousRequest.setup() BusinessProcess Line 58 BusinessProcess.instance().resumeTask(taskId); BusinessProcess.resumeTask() BusinessProcess Line 252 TaskInstance task = org.jboss.seam.bpm.TaskInstance.instance(); TaskInstance.getTaskInstance() TaskInstance Line 39 return new Work<org.jbpm.taskmgmt.exe.TaskInstance>() Work.workInTransaction() Work Line 44 userTransaction.begin() EntityTransaction.begin() EntityTransaction Line 79 initEntityManager() EntityTransaction Line 67 entityManager.getValue() Contexts.lookupInStatefulContexts("entityManager") Contexts Line 209 getBusinessProcessContext() BusinessProcessContext.get("entityManager") BusinessProcessContext Line 65 getTaskInstance() BusinessProcessContext Line 241 TaskInstance.instance() TaskInstance.instance() TaskInstance Line 64 Component.getInstance(TaskInstance.class, ScopeType.STATELESS) --> going to unwrap TaskInstance.getTaskInstance() --> endless loop Please assist Gena -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
