/**
* This class is responsible mainly for executing ejbc.
* It also does the following:
* <pre>
* - constructs the class loader for the deployed app
* - loads the deployment descriptors
* - calls ejbc
* - sets the unique id
* - writes the deployment descriptors
*
* classpath: Ejbc reads the target instance's classpath-prefix and
* classpath-suffix via config context. It creates a class loader
* hierarchy based on these class paths, common class loader urls
* ($INSTANCE/lib/classes:$INSTANCE/lib/*.jar:$INSTANCE/lib/*.zip)
* and the application's urls.
*
* BootStrap<-System<-Common<-Share<-Ejb<-Servlet<-Jasper [Admin Server]
* |
* |<-(classpath-prefix+classpath-suffix)<-Common<-Shared<-Ejb [EJBC]
*
* Note that System classpath is shared between the two hierarchy.
* According to the architect, end users are not expected to replace the
* Application Server's jar (for example, appserv-rt.jar, etc). So, it is
* sufficient to include the classpath-prefix and classpath-suffix in the
* ejbc class loader hierarchy. Any system level jar should be replaced
* accross all server instances.
*
* S1AS8 Change:
* Deployment no longer needs to pick up class paths from target
* server instance. Deployment class paths contains only the DAS's
* class path plus the whole application paths.
*
* rmic-options: Ejbc reads rmic options from server xml. If none found, it
* gets the default from DTD.
*
* javac-options: Ejbc reads javac options from server xml. It supports
* the "-g" and "-O" options.
* </pre>
