* CWE: 319 Cleartext Transmission of Sensitive Information
* BadSource: URLConnection Read password from a web server with URLConnection
* GoodSource: Set password to a hardcoded value (one that was not sent over the network)
* Sinks: driverManager
*    GoodSink: Decrypt the password from the source before using it in database connection
*    BadSink : Use password directly from source in database connection
* Flow Variant: 14 Control flow: if(IO.staticFive==5) and if(IO.staticFive!=5)
