Description

When activating a component, the AbstractComponentManager#activateInternal method checks some properties, then grab the lock and actually activate the component, leaving a gap between the check and the lock being acquired, which can result in the component being deactivated in the mean time, ultimately leading to NPE because m_tracker has been nulled.
