>             Project: Derby
>          Issue Type: Bug
>          Components: JDBC, Network Client
>    Affects Versions: 10.3.1.4
>         Environment: Client driver on most platforms
>            Reporter: Olav Sandstaa
>            Priority: Minor

> Setting the login timeout by using DriverManager.setLoginTimeout(int
> seconds) also affects the amount of time the client driver is waiting
> for a query to finish. For instance, setting the login timeout to 10
> seconds will result in any queries taking more than 10 seconds to fail
> with the following exception:
> Exception thrown: java.sql.SQLException: A communications error has been detected: Read timed out.
> java.sql.SQLException: A communications error has been detected: Read timed out.
