JPAWorkingMemoryDbLogger logger stoped working
In my project I'm working with jbpm 5.3, drools and servicemix. Recently I started getting errors when servicemix jbpm bundle is trying to create JPAWorkingMemoryDbLogger logger = new JPAWorkingMemoryDbLogger(ksession);
Any ideas what could cause the problem
