By aledsage:

BlobStoreFileObject:98 use lower-case first letter for parameter names, rather than "BlobBuilderName"
Also, fail early if you're going to fail. You could do checkNotNull(name,"No name specified") in the constructor rather than waiting until onClose to throw the exception. Then the stack trace will show where the null came from.
Is there a better name than "outputFiles" for the builder name? It being plural seems strange...
Any reason to have the bulider as a field, rather than a local variable of the method?
