   Reason analyze:
   
   **jpa code:**
   debug info:
   class:Loader.java
   method:processResultSet
   
   **this rs.next() call two times,  result list size is two，finally jpa throw error；**
   rs：ShardingResultSet   call    IteratorStreamMergedResult
   
   
   ```
   for ( count = 0; count < maxRows && rs.next(); count++ ) {
   			if ( DEBUG_ENABLED ) {
   				LOG.debugf( "Result set row: %s", count );
   			}
   			Object result = getRowFromResultSet(
   					rs,
   					session,
   					queryParameters,
   					lockModesArray,
   					optionalObjectKey,
   					hydratedObjects,
   					keys,
   					returnProxies,
   					forcedResultTransformer
   			);
   			results.add( result );
   			if ( createSubselects ) {
   				subselectResultKeys.add( keys );
   				keys = new EntityKey[entitySpan]; //can't reuse in this case
   			}
   		}
   ```
