This issue is caused by https://github.com/apache/incubator-shardingsphere/issues/3231.
max.connections.size.per.query=1 means Proxy will use MemoryQueryResult in this full routing case.
In MemoryQueryResult.java:
`return metaData.isSigned(columnIndex) ? resultSet.getInt(columnIndex) : resultSet.getLong(columnIndex);
`
This line will anyhow return a Long Object instead an Integer Object or a Long object. Proxy will burst an exception if the data type is inconsistent.
