Prevent deadlock with Framework
-------------------------------
Key: SLING-2420
URL: https://issues.apache.org/jira/browse/SLING-2420
Project: Sling
Issue Type: Improvement
Components: Extensions
Affects Versions: i18n 2.2.0
Reporter: Felix Meschberger
Assignee: Felix Meschberger
Fix For: i18n 2.2.2
JcrResourceBundleProvider may cause a deadlock between itself and the OSGi
Framework:
* clearCache is called from framework and synchronizes on itself while calling
into the framework
* getResoureBundleInternal synchronizes on itself and calls into the framework
Fixes:
- clearCache synchronizes on self to get a copy of the service registration
list and clears the list; the services are unregistered outside of the sync
- getResourceBundleInternal only stores the service registration in the
internal list in the synchronized block
