             Summary: IndexingConfigurationBuilder query module validation is wrong
                 Key: ISPN-4639
                 URL: https://issues.jboss.org/browse/ISPN-4639
             Project: Infinispan
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Configuration
    Affects Versions: 7.0.0.Beta1
            Reporter: Paul Ferraro
            Assignee: Dan Berindei


The query module is ultimately loaded by the ComponentRegistry, which will load its modules via the classloader returned by GlobalConfiguration.classLoader().  However, the logic in IndexingConfigurationBuilder.validate(...) tests that the query module classes are accessible from the classloader that loaded the IndexingConfigurationBuilder itself.

In WildFly, to use querying, one would use the following configuration:
<cache-container module="org.infinispan.query"/>
Internally, this configures Infinispan's GlobalConfiguration with the classloader of the "org.infinispan.query" module.
However, the IndexingConfigurationBuilder class is contained in the "org.infinispan" - which does not depend on the "org.infinispan.query" module.  Consequently, IndexingConfigurationBuilder validation fails, even though the module would have been successfully loaded at runtime.
