SystemProperties (OpenNMS 2020.1.14 API)

```
public class SystemProperties
extends Object
```
Utility to extract system properties, similar to Integer.getInteger. This class allows to distinguish between a none present value and a malformed value. In case of the latter a log message is produced. Integer.getInteger would just return the defaultValue without informing the user and can therefor lead to hard to find configuration problems.
