We cannot depend on SE 7 :-( [*]

I think that could be useful when one wants to reuse an existing
exception rather than catching and throwing WebApplicationException or a
subtype of.

Note that in Jersey i have extended WebApplicationException for some
common errors like NotFoundException.

Paul.

[*] I wish 308 specify the creation of default annotations for method
parameters with values that are the names of those method parameters, so
we can do this:

    @QueryParam String foo

instead of repeating "foo" like this:

    @QueryParam("foo") String foo
