/**
 * This RuntimeBuilder can only handle GlassFish_Platform of following types:
 * 
 * {@link Constants.Platform#Felix},
 * {@link Constants.Platform#Equinox},
 * and {@link Constants.Platform#Knopflerfish}.
 *
 * <p/>It can't handle GenericOSGi platform,
 * because it reads framework configuration from a framework specific file when it calls
 * {@link ASMainHelper#buildStartupContext(java.util.Properties)}.
 *
 * This class is responsible for
 * a) setting up OSGi framework,
 * b) installing glassfish bundles,
 * c) starting the primordial GlassFish bundle (i.e., GlassFish Kernel bundle),
 * d) obtaining a reference to GlassFishRuntime OSGi service.
 * <p/>
 * Steps #b & #c are handled via {@link AutoProcessor}.
 * We specify our provisioning bundle details in the properties object that's used to boostrap
 * the system. AutoProcessor installs and starts such bundles, The provisioning bundle is also configured
 * via the same properties object.
 * <p/>
 * If caller does not pass in a properly populated properties object, we assume that we are
 * running against an existing installation of glassfish and set appropriate default values.
 * <p/>
 * <p/>
 * This class is registered as a provider of RuntimeBuilder using META-INF/services file.
