public class ClassLoaderUtils - extends Object
This class is extremely useful for loading resources and classes in a fault tolerant manner
that works across different applications servers.
It has come out of many months of frustrating use of multiple application servers at Atlassian,
please don't change things unless you're sure they're not going to break in one server or another!
