OOME on servlet container redeployment
--------------------------------------

                 Key: WBRI-405
                 URL: https://jira.jboss.org/jira/browse/WBRI-405
             Project: Web Beans
          Issue Type: Bug
          Components: Web Tier integration (JSF, JSP, EL and Servlet)
            Reporter: Christian Bauer
            Priority: Critical


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] 07:57:55,881 DEBUG [org.jboss.webbeans.bootstrap.WebBeansBootstrap] Web Beans initialized. Validating beans.

(Had to stop the process with KILL signal.)

Sometimes it doesn't hang and I get this instead:
