AttributeHolderInitException?

From what I can tell from some out-of-sync doc comments in the Jigsaw code,
it looks like the code for AttributeHolder.initialize() used to throw
AttributeHolderInitException, but has been changed to throw no exceptions.
I think it might have been better to allow for such an exception to be
thrown.

I am trying to create a subclass of FilteredResource that may need to throw
an exception if it isn't initialized properly.  The way initialize() is
declared now, I can't do that.  I think it makes sense for an
AttributeHolder to be responsible for detecting when it receives
inappropriate initialization parameters, but for the initializing object to
be responsible for handling that exception appropriately.

Sounds like a job for Java's exception-handling mechanism, yes?
