> A TransformerFactory for a global transformer might return null for the Transformer, similar the factory might already be gone. Both result in a null value inserted into the array of global transformers.
> Later on, when that array is processed, there is no null check anymore. Potentially resulting in a NullPointerException
> This should be guarded with a null check, as this might happen in a dynamic system
