Hi all,
I found a way to solve my issue and load the jbpm session correctly, but I'm still looking for a better solution.
the workaround : creating a new ksession , KnowledgeBaseFactory.newKnowledgeSessionConfiguration(sessionconfigproperties)
By copping the content of rulesbytearray (sessionInfo table) of the new created session in the rulesbytearray of old ksession instance that can not be load and restarting the application, every thing work just fine.
Please if any one think that this can cause an issue or have any other solution, please let me know.
Many thanks.
