* CWE: 400 Resource Exhaustion
* BadSource: Property Read count from a system property
* GoodSource: A hardcoded non-zero, non-min, non-max, even number
* Sinks:
*    GoodSink: Validate count before using it as a parameter in sleep function
*    BadSink : Use count as the parameter for sleep withhout checking it's size first
