visit: https://community.jboss.org/message/823396#823396 -------------------------------------------------------------- Hi, I try to use JBPM5.4, Spring 3.1.4, Hibernate 4.1.9, Jboss AS 7.1.1 and JBoss Transaction Manager I create a simple function to start a process When I just have 1 thread calling that function, everything works fine But when I have 2 thread calling the function concurrently, I will get this error 13:54:40,867 ERROR [org.hibernate.AssertionFailure] (pool-28-thread-1) HHH000099: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session): org.hibernate.AssertionFailure: null id in org.jbpm.persistence.processinstance.ProcessInstanceInfo entry (don't flush the Session after an exception occurs)
