[gatein-issues] [JBoss JIRA] Commented: (GTNPORTAL-2088) Infinite loop when edit banner portlet with invalid value

[Thomas Heute (JIRA)]

    [ https://issues.jboss.org/browse/GTNPORTAL-2088?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12627539#comment-12627539 ] 

Thomas Heute commented on GTNPORTAL-2088:
-----------------------------------------

Indeed, with an invalid URI:

It loops over
   public ResourceResolver getResourceResolver(String uri)
   {
      Application app = getApplication();
      while (app != null)
      {
         ApplicationResourceResolver appResolver = app.getResourceResolver();
         ResourceResolver resolver = appResolver.getResourceResolver(uri);
         if (resolver != null)
            return resolver;
         RequestContext pcontext = getParentAppRequestContext();
         if (pcontext != null)
            app = pcontext.getApplication();
         else
            app = null;
      }
      return null;

since pcontext.getApplication() returns the same value for app as before.

> When you edit banner portlet with invalid value, close & open browser -> you are not able to access portal.
> With each refresh it takes another database connection and after 20 attempts you end up with:
> 13:20:10,748 ERROR [JDBCExceptionReporter] Unable to get managed connection for gatein-idm; - nested throwable: (javax.resource.ResourceException: Unable to get managed connection for gatein-idm)
> I'm also attaching thread dump where you can see that 20 threads are running in following classes:
> at java.util.HashMap.get(HashMap.java:300)
> at org.exoplatform.resolver.ApplicationResourceResolver.getResourceResolver(ApplicationResourceResolver.java:70)
> at org.exoplatform.webui.application.WebuiRequestContext.getResourceResolver(WebuiRequestContext.java:184)
> I think there is problem with while loop in WebuiRequestContext.getResourceResolver method.
