Currently, only ClientProperties, ServerProperties, and CommonProperties properties are used for properties defined by system properties grabbed when SecurityManager is on.
It would make sense to try other @PropertiesClass annotated property classes.

If I understand it correctly:
The current class SystemPropertiesConfiguration.getExpectedSystemProperties() is only loading the fields from CommonProperties, CommonProperties and ClientProperties.

And we want to add any existing class having the annotation @PropertiesClass or
@Property

I think there is no point to search by reflection inside of a package, because we only include these annotated classes inside jersey.
