I agree with Craig's suggestion here; a custom rule will do the trick
nicely. It might also be possible to register a custom String->int[]
converter for beanutils, but I have some vague memory that there's a
problem with that.

Actually, SetPropertiesRule has the ability to specify explicit
attrname->propname mappings. Mapping to a null property causes the
attribute to be ignored. As you only need to override one particular
attribute you should be able to do:
d.addSetProperties("List/C", "depends", null);
to map all attributes to identically named properties *except* the
depends property which will be ignored (and processed by your custom
rule instead).
