You'd have to change the code anyway, and IMO it's messier and more
error-prone to use hard-coded strings like you're doing.

When I run across something like that I take the following approach:
Q: Why am I getting a class-cast exception?
A: I'm getting String[] instead of a single String.
Q: What's in the String[] I'm actually getting?
A: [Uses logging or debugger to find out]
That's usually enough to answer the question.
