[JBoss JIRA] (ISPN-9917) JCachingProvider should not use weak ClassLoader references
by Dan Berindei (Jira)
[ https://issues.jboss.org/browse/ISPN-9917?page=com.atlassian.jira.plugin.... ]
Dan Berindei updated ISPN-9917:
-------------------------------
Description:
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. However, this approach causes problems when a test creates a temporary {{ClassLoader}} instance and calls {{Caching.getCachingProvider().getCacheManager(tempClassLoader)}}, because the JVM is free to collect {{tempClassLoader}} immediately after it's used to create the {{WeakClassLoader}}. This can cause failures in the jcache tck with the IBM JDK:
