Major Description
TagLibraryConfig.containsTagHandler search a composite component file like:
ResourceHandler resourceHandler =
FacesContext.getCurrentInstance().getApplication().getResourceHandler();
Resource compositeComponentResource = resourceHandler.createResource(
localName +".xhtml", _compositeLibraryName);
But never checks if the name space is the same as requested, so method returns 'true' if same tag name exist on different name space.
Then null pointer is thrown when building component tree:

A check like:

Is not needed previous to facelet file search?
