Release Notes Text: Removed: "Cannot find the configuration for the component org.exoplatform.portal.webui.container.UIContainerList, configId null" could be logged under heavy load. Added: The use of HashMap in the ConfigurationManager class for multithreaded environments in previous versions of EPP caused the following message to appear in logs while using the product under heavy load: "java.lang.Exception: Cannot find the configuration for the component org.exoplatform.portal.webui.container.UIContainerList, configId null".

In the latest release, HashMap has been replaced with ConcurrentHashMap, which accepts default values for initial capacity, load factor and concurrencyLevel and resolves the exception.
