                 URL: https://jira.jboss.org/jira/browse/GTNPORTAL-599
             Project: GateIn Portal
          Issue Type: Bug
    Affects Versions: 3.0.0-Beta05
         Environment: - Tomcat server
            Reporter: Trong Tran
             Fix For: 3.0.0-CR01


When i stop Tomcat i have got this :

java.util.ConcurrentModificationException
	at java.util.AbstractList$Itr.checkForComodification(AbstractList.java:372)
	at java.util.AbstractList$Itr.next(AbstractList.java:343)
	at org.exoplatform.web.application.javascript.JavascriptConfigService.removeJavascript(JavascriptConfigService.java:192)
	at org.exoplatform.web.application.javascript.JavascriptRemoval.removeJavascript(JavascriptRemoval.java:76)
	at org.exoplatform.web.application.javascript.JavascriptRemoval.onEvent(JavascriptRemoval.java:59)
	at org.gatein.wci.impl.DefaultServletContainer.safeFireEvent(DefaultServletContainer.java:147)

Also, I have got a similar problem when i try to undeploy the eXoResources.war which contains the Javascripts used in Portal.

the problem seems to be evident that we ismodifing a Collection while iterating over it.
