[webbeans-issues] [JBoss JIRA] Commented: (WBRI-405) OOME on servlet container redeployment

OOME on servlet container redeployment -------------------------------------- Key: WBRI-405 URL: https://jira.jboss.org/jira/browse/WBRI-405 Project: Web Beans Issue Type: Bug Reporter: Christian Bauer Priority: Critical Fix For: 1.0.0.CR2 Redeploying /examples/wicket/numberguess (no code changes, just repeated deploy/undeploy cycles) to Jetty, running from within IntelliJ but in a separate VM. With default max heap size (JConsole reports 84 MB) after 3 redeployment cycles or with Xmx256m after about 10 cycles, the VM simply hangs at 100% CPU load with a full heap and the log: [Timer-1] 07:57:54,804 DEBUG [org.jboss.webbeans.bootstrap.AbstractBeanDeployer] Bean: Built-in implicit javax.inject.Instance bean [Timer-1] 07:57:54,805 DEBUG [org.jboss.webbeans.bootstrap.AbstractBeanDeployer] Bean: org.jboss.webbeans.bean-web-module-NewManagedBean-org.jboss.webbeans.wicket.BeanManagerLookup [Timer-1] 07:57:54,806 DEBUG [org.jboss.webbeans.bootstrap.AbstractBeanDeployer] Bean: org.jboss.webbeans.bean-web-module-NewManagedBean-org.jboss.webbeans.conversation.NumericConversationIdGenerator [Timer-1] 07:57:55,879 DEBUG [org.jboss.webbeans.bootstrap.AbstractBeanDeployer] Bean: org.jboss.webbeans.bean-web-module-NewManagedBean-org.teleal.hub.bookmarks.ui.HelloWorld [Timer-1] 07:57:55,881 DEBUG [org.jboss.webbeans.bootstrap.WebBeansBootstrap] Web Beans initialized.
