Exception on differenceResult.getSourceSchema().getDatabase().findTable(missingTable.getLeftName(), false)

[AbdelhalimSAP]

Please add a null test in DefaultDatabaseSchemaDifferenceService l236 as thise causes an exception :

if(differenceResult.getSourceSchema().getDatabase().findTable(missingTable.getLeftName(), false) == null){
                    LOG.warn("Error findTable=["+missingTable.getLeftName()+"]");
                    continue;
                }
