Streaming query swallowing SQLException

[Don Mitchell]

Intermittent errors from our code are being swallowed someplace during streaming and causing the streaming to hang. I'm fairly certain it's occurring under `ResultSet.next`.

Is this a known problem? Is there a known workaround? We've tried catching and rethrowing the errors as other errors. They get caught but they still get muted.

Can someone point me to the streaming implementation of `ResultSet.next`? It's probably not actually that but whatever implements `this.rowData.next()`. I am curious whether com.mysql.cj.jdbc.result.ResultSetImpl#clearWarnings may be a causal agent.

The kotlin version of the iteration with annotation
``` kotlin
database.dirtyExecuteExpression(expression) { statement ->
logger.debug { "Running query: $statement" }
if (database.dialect is MySqlDialect) statement.fetchSize = Integer.MIN_VALUE
statement.queryTimeout = 0 // no timeout
try {
statement.executeQuery().use { rs ->
logger.debug { "Query: $rs" }
while (rs.next()) {
try {
action(rs)
} catch (e: SQLException) {
// catches the error but the throw hangs rather than exits the iteration
logger.error(e) { "Error during suspendable query $statement on ${statement.connection}" }
throw e
}
}
}
} catch (e: SQLException) {
// catches the eventual socket disconnect error
logger.error(e) { "Outer error during suspendable query $statement on ${statement.connection}" }
throw e
}
}
```
