Carsten Ziegeler created SLING-4497:
---------------------------------------
Summary: Memory thread might be terminated by already unregistered
bundles/services
Key: SLING-4497
URL: https://issues.apache.org/jira/browse/SLING-4497
Project: Sling
Issue Type: Bug
Components: ResourceResolver
Affects Versions: Resource Resolver 1.2.0
Reporter: Carsten Ziegeler
Assignee: Carsten Ziegeler
Fix For: Resource Resolver 1.2.2
The memory thread in the common resource resolver factory calls close on the
resource context which in turn tries to close all providers and the used type
resource resolver.
If an exception occurs during this, like it might happen on bundle stop (see
below), the memory thread dies which in turn might lead to a memory issue.
java.lang.IllegalStateException: Invalid BundleContext.
