Rupert Westenthaler created STANBOL-1323:
--------------------------------------------
Summary: Change ConfigurationPolicy of all EntityDereferencer and
EntitySearcher ComponentFactories to OPTIONAL
Key: STANBOL-1323
URL: https://issues.apache.org/jira/browse/STANBOL-1323
Project: Stanbol
Issue Type: Bug
Components: Entityhub
Reporter: Rupert Westenthaler
Assignee: Rupert Westenthaler
Fix For: 1.0.0, 0.12.1
All EntityDereferencer and EntitySearcher implementations (all of them in the
entityhub.site.linkeddata module) have used ConfigurationPolicy.REQUIRE since
the beginning. The idea was that instances created with this ComponentFactories
do require a configuration. However that is not the intention of the
annotation. The annotation defines if the factory needs a configuration. As
this is not required the correct annotation is ConfigurationPolicy.OPTIONAL.
Before STANBOL-1322 this was not an issue as the used Felix version had ignored
the configuration policy for ComponentFactories. However after the version
update this is no longer the case and the therefore no ComponentFactories for
EntityDereferencer and EntitySearcher where created.
Because of that no Entityhub ReferencedSite with configured EntitySearcher or
EntityDereferencer could be created.
To Solve this one needs to changte the ConfigurationPolicy annotation of all
EntityDereferencer and EntitySearcher implementations from REQUIRE to OPTIONAL
(the default).
