1. OSCAR first looks for the System.Properties file with oscar.jar in the same directory, load all system properties.
You can change the path to the System.Properties file by setting an OSCar.System.Properties property.
2. Find the value of cache_profile_prop to determine the Profile name property;
Find values for cache_profile_dir_prop Determine the Profile directory properties.
3, OSCAR Other Attributes Setting [Option]
4, instantiate OSCAR
1) Create a copy of the incoming configuration properties
m_configpropmap = new hashmap ();
For (Enumeration E = Props.propertyNames (); E.haASMoreElements ();)
{
String name = (string) E.NEXTELEMENT ();
m_configpropmap.put (name, props.getproperty);
}
2) Instantiate the cache instance of bundle bundle [Analysis] if the cache_class_prop system property is not specified, then instantiate the defaultbundlecache.
When an exception occurs during this process, the JVM is stopped if OSCAR is started independently.
3) Initialize the OSCAR instance

Construct an ImportSearchPolicy instance [Analysis]. ImportSearchPolicy implements ModuleLoader's finding policies to support modules mutual import and resources.

Registering an OSGi Selection Policy instance on ModuleManager as a Module listening to the Module to clean Package Export Cache when modules are uninstalled.
Register Validation listening on the ImportSearchPolicy instance so that when Modules is updated after Validated (such as resolved).

Create a system bundle instance:
Simple bundle info instance for System Bundle [Todo: Analysis Bundleinfo Construction]
Instantiate System Bundle [Todo: Analysis of Systembundle Construction]
Put System Bundle in Installed Bundle Map
Call the ImportSearchPolicy instance to the Validate System bundle to make its status as resolved. 【analysis】
Launch System Bundle [Analysis]
Re-load and cache bundles

Get the default Start Level
Load bundles from Auto-INSTALL and Auto-Start Properties;
ProcessAutoproperties (); [Analysis]
Set the Active Start Level of Framework, if necessary, you may restart your bundles.
SetStartLevel (StartLevel); [Analysis]
OSCAR enters the start state
m_oscarstatus = running_status;
Set the State of System Bundle to active.systemBundle.GetInfo (). SetState (bundle.active);
Trigger Started Event for System Bundle.
Firebundleevent (bundleevent.started, systembundle);
Send a Framework Event indicates that OSCAR has started.
FirefraMeworKevent (frameworkevent.started, getBundle (0), NULL);
