we use JBPM-3.1.2 and the DataBase is Oracle 9i ,jdk1.4.2
when I deploy a processdefinition, the hibernate didn't tell any Exception. but when I check the data in the DataBase, I find that: the node which type is R(Start-node) or E(End-node) miss its processdefinition. In the table which named 'JBPM-NODE' ,the FIELD 'PROCESSDEFINITION_' is null,which node type is R or E, but other node is right.
it didn't happen all the time, some times, when I deploy again,this problem is disappear.
