> When AbstractComponent.getComponents(String) is called the HashMap "_components" is unexpectedly null, causing an ApplicationRuntimeException which indicates that the given component (id passed as parameter to getComponents(String)), does not exist. We have confirmed that in every instance the given component does exist in the given page.  
> This problem happens randomly on a variety of pages.  
> This could be an indication of a thread safety problem in the PageLoader class. We can duplicate the problem, (unreliably), via our selenium test suite.
