Add the following code snippet to BaseStagedModelDataHandlerTestCase and run the MBMessageStagedModelDataHandlerTest.

 

@Test
public void testDoubleExportImport() throws Exception {
   Map<String, List<StagedModel>> dependentStagedModelsMap =
      addDependentStagedModelsMap(stagingGroup);

   StagedModel stagedModel = addStagedModel(
      stagingGroup, dependentStagedModelsMap);

   exportImportStagedModel(stagedModel);

   StagedModel importedStagedModel = getStagedModel(
      stagedModel.getUuid(), liveGroup);

   Assert.assertNotNull(importedStagedModel);

   exportImportStagedModel(stagedModel);

   importedStagedModel = getStagedModel(stagedModel.getUuid(), liveGroup);

   Assert.assertNotNull(importedStagedModel);
}

The problem is when the message has an attachment and we import the same lar with this message two times to the same destination, the import fails with this exception:
