Shouldn't this be using Thread.currentThread().classLoader()? The previous call (inside the try... catch) was using this class classLoader.. if you catch an exception and try, I would expect to do somethng different.. like using the classLoader, not doing the same operation. it seems a typo to me... can you check?
