Not all client code is compiled with NullAway.
Do not make a parameter `@Nullable` just to check and throw a `NullPointerException` when it is `null`. 

## Consequences

* Classes are forced to have consistent nullability annotations.
* IDE warnings become more accurate, reducing warnings fatigue.
* Public API nullability annotations become closer to reality.

     * a different Properties object/file to be used as the source of properties for
     * use by the jCIFS library. The Properties must be set <i>before jCIFS
     * classes are accessed</i> as most jCIFS classes load properties statically once.
     * Using this method will also override properties loaded
     * using the <code>-Djcifs.properties=</code> commandline parameter.
