                                        FileNotFoundException

Extract native library from jar in a working directory, load and link it. The 'lib-vendor' folder in 'scm-x.x.x.jar' file is searched for the required native library for vendor specific communication. It also load vendor's native shared library.

Parameters:

libDirectory - directory in which native library will be extracted and vendor library will be found

vlibName - name of vendor library to load and link

cpuArch - architecture of CPU this library is running on

osType - operating system this library is running on

serialComSystemProperty - instance of SerialComSystemProperty to get required java properties

Throws:

SerialComUnexpectedException - if a critical java system property is null in system

SecurityException - if any java system property can not be accessed

FileNotFoundException - if the vendor library file is not found

SerialComLoadException - if any file system related issue occurs

UnsatisfiedLinkError - if loading/linking shared library fails
