All Implemented Interfaces:

Configurable, Contextualizable
```
public class LostInstanceCheck
extends AbstractAddonsCheck
```
Checks that object instances created explicitly with new are actually used for something. Just being assigned to a variable or passed as a parameter is enough. A full data flow analysis is not performed.
