----------------------------------

             Summary: JCachingProvider should not use weak ClassLoader references
                 Key: ISPN-9917
                 URL: https://issues.jboss.org/browse/ISPN-9917
             Project: Infinispan
          Issue Type: Bug
          Components: JCache
    Affects Versions: 9.4.6.Final, 10.0.0.Alpha3
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 10.0.0.Beta1, 9.4.7.Final


The idea behind {{WeakClassLoader}} is that we want users to be able to use {{Caching.getCachingProvider().getCacheManager()}} and not worry about closing the cache manager: instead Infinispan will close the manager when there are no more references to the provided {{ClassLoader}}.

In order to close the manager automatically, {{AbstractJCachingProvider}} maintains a {{WeakHashMap}} of classloaders to managers, and if the cache manager had a strong reference to the classloader, the {{WeakHashMap}} entry would never be collected.
