The code expects getTimeZone to return null in the event that a timezone cannot be found. It in fact returns GMT. This is, IMHO, a bug in Java. But good luck getting Oracle to do anything about it.

I propose replacing the null check with a check for GMT. No real feeds should use GMT; instead they should use Europe/London or whatever.
