/**
* This class is used for executing processes that are in an envronment that has a VERY limited
* command line execute size. The links off the start menu in windows has a maximum size of 259 characters.
* The PLBootstart requires that appserver installroot path is in the command twice and
* the java installroot is the in the command once, so allowance have to be given for user directory location
* preference. The reason, PLBoostrap is not placed inside a package is to keep the command size as small as possible.
* The associated properties file holds the classpath and property information requirer to setup the
* com.sun.enterprise.tools.ProcessLauncer environment.
