Method

java.lang.Object
- com.sun.jersey.core.osgi.OsgiRegistry

All Implemented Interfaces:

java.util.EventListener, org.osgi.framework.BundleListener, org.osgi.framework.SynchronousBundleListener
```
public final class OsgiRegistry
extends java.lang.Object
implements org.osgi.framework.SynchronousBundleListener
```
Utility class to deal with OSGi runtime specific behavior. This is mainly to handle META-INF/services lookup and generic/application class lookup issue in OSGi. When OSGi runtime is detected by the ReflectionHelper class, an instance of OsgiRegistry is created and associated with given OSGi BundleContext. META-INF/services entries are then being accessed via the OSGi Bundle API as direct ClassLoader#getResource() method invocation does not work in this case within OSGi.
