Bonjour Madame / Monsieur: I am trying to load an old simulation that was originally ran in isis-fish 4.4.2.5. I am unsure what this following error message corresponds to though: _fr.ifremer.isisfish.IsisFishRuntimeException: Can't load old simulation_ _ at fr.ifremer.isisfish.ui.simulator.ParamsHandler.loadOldSimulation(ParamsHandler.java:236)_ _ at fr.ifremer.isisfish.ui.simulator.ParamsHandler.lambda$loadOldSimulation$2(ParamsHandler.java:324)_ _ at java.awt.event.InvocationEvent.dispatch(Unknown Source)_ _ at java.awt.EventQueue.dispatchEventImpl(Unknown Source)_ _ at java.awt.EventQueue.access$500(Unknown Source)_ _ at java.awt.EventQueue$3.run(Unknown Source)_ _ at java.awt.EventQueue$3.run(Unknown Source)_ _ at java.security.AccessController.doPrivileged(Native Method)_ _ at java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(Unknown Source)_ _ at java.awt.EventQueue.dispatchEvent(Unknown Source)_ _ at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source)_ _ at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source)_ _ at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source)_ _ at java.awt.EventDispatchThread.pumpEvents(Unknown Source)_ _ at java.awt.EventDispatchThread.pumpEvents(Unknown Source)_ _ at java.awt.EventDispatchThread.run(Unknown Source)_ _Caused by: java.lang.NullPointerException_ _ at jaxx.runtime.context.DefaultJAXXContext.setContextValue(DefaultJAXXContext.java:77)_ _ at jaxx.runtime.context.DefaultJAXXContext.setContextValue(DefaultJAXXContext.java:72)_ _ at fr.ifremer.isisfish.ui.simulator.SimulatorContext.setRegionStorage(SimulatorContext.java:86)_ _ at fr.ifremer.isisfish.ui.simulator.ParamsHandler.loadOldSimulation(ParamsHandler.java:211)_ _ ... 15 more_ Can you help or troubleshoot this issue?
