Cache container enable statistics can lead to classloader leak -------------------------------------------------------------- Key: WFLY-6685 URL: https://issues.jboss.org/browse/WFLY-6685 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 10.0.0.Final Reporter: Mathieu Lachance Assignee: Paul Ferraro In standalone.xml, if we enable statistics such as: {code} <cache-container name="web" default-cache="repl" module="org.wildfly.clustering.web.infinispan" statistics-enabled="true"> <transport lock-timeout="60000"/> <replicated-cache name="repl" statistics-enabled="true" mode="ASYNC"> <locking isolation="READ_COMMITTED"/> <transaction locking="OPTIMISTIC" mode="BATCH"/> <state-transfer chunk-size="512" timeout="240000"/> </replicated-cache> </cache-container> {code} The following MBean: {code} jboss.infinispan:cluster=web,type=channel {code} is getting eventually registered when deploying any application. When undeploying that application, the MBean is not getting unregistered and thus can leak pretty much anything. Also, if you try to deploy the very same application right after another MBean will get registered: {code} jboss.infinispan2:cluster=web,type=channel {code} Note: cache enable-statistics=true doesn't seems to leak anything.
