Lack of EmbeddedCacheManager.undefineConfiguration(String) can cause memory/classloader leaks --------------------------------------------------------------------------------------------- Key: WFLY-5436 URL: https://issues.jboss.org/browse/WFLY-5436 Project: WildFly Issue Type: Bug Components: Clustering Reporter: Paul Ferraro Assignee: Paul Ferraro Priority: Critical Fix For: 10.0.0.Final EmbeddedCacheManager has defineConfiguration(...) methods for defining a new cache configuration, but has no equivalent "undefine" method. Consequently, once defined, a cache manager will retains a reference to the cache configuration object for the lifetime of the cache manager. While this is normally not a big deal, the configuration objects generated by WildFly contain references to the classloaders of foreign modules.
