### Describe the bug, including details regarding any error messages,

When using the Flight JDBC driver on Linux (JDBC version 10.0.0, Ubuntu
22.04, using DBeaver 22.3.2 as the JDBC GUI) with a secure endpoint, a
NullPointerException is thrown.

```
It seems to be caused by the driver requiring a trust store password on
Linux, even though that shouldn't be required. A workaround that seems to work
is specifying the connection URI as
`jdbc:arrow-flight://<SERVER.NAME>:32010/?trustStorePassword=changeit`
