Currently the Class:
jbpm-gwt/jbpm-gwt-core/src/main/java/org/jbpm/integration/console/TaskManagement.java
establishes a connection to the TaskService only if the TaskService is null. This works fine, but if the underlying human task service is restarted, the connection becomes invalid and tasks are not handled. Errors are not thrown. It would be nice to throw and log appropriate errors if the service is not null but not connected, it would also be nice to try to reconnect.
