All Implemented Interfaces:

public class CrowdOsgiContainerManager extends com.atlassian.plugin.osgi.container.felix.FelixOsgiContainerManager
OSGI container manager that caches service trackers. This is necessary to avoid creating ServiceTracker instances willy nilly, while at the same time circumventing a memory leak in FelixOsgiContainerManager (JRA-18766).

    • getOsgiComponentOfType

      public <T> T getOsgiComponentOfType(Class<T> clazz)
      Retrieves and returns a public component from OSGi land via its class or interface name. This method can be used to retrieve a component provided via a plugins2 OSGi bundle. Please note that components returned via this method should NEVER be cached (e.g. in a field) as they may be refreshed at any time as a plugin is enabled/disabled or the ComponentManager is reinitialised (after an XML import).

      Added as part of the fix for JRADEV-6195.

      Parameters:
      clazz - The interface class as a String
      Returns:
      the component, or null if not found

Please note that components returned via this method should NEVER be cached (e.g. in a field) as they may be refreshed at any time as a plugin is enabled/disabled or the ComponentManager is reinitialised (after an XML import).
      Parameters:
