/**
 * This option can be used to define the contents of a JAR probe for CDI test containers. When a JAR
 * probe option is present, the test container builds a JAR on the fly, creates a classloader for
 * this JAR and uses this as thread context classloader while the container is running.
 * 
 * Otherwise, when no JAR probe option is present, the CDI test container simply uses the system
 * classloader.
 * 

 * Users should create instances of this class using {@link CoreOptions#jarProbe()} and then invoke
 * methods of this class in fluent syntax to configure the JAR probe.
