What are those ".so" files? What is your OS?

I'm wondering if the driver is dropping shared libraries onto the disk
and then loading them using e.g. System.loadLibrary.

As far as I know, it is not possible to System.unloadLibrary, so weird
things might happen if/when you try to load the JDBC driver multiple
times. Even loading it once might end up with files that the JVM/OS is
unwilling to unlock.
