BAH, it works fine. Sorry for the noise.
I once again forgot to install the assisted object factory in the
JerseyServletModule. It was a simple mistake but it produced a fairly
unhelpful stack trace.
For those who encounter this in the future, what I forgot to do was
(in the module):
install(new FactoryModuleBuilder().build(DbLogSubResource.Factory.class));
