JAXB tends to not work very well with Collections/Lists IMO - at least not
right on the parameter class. You may want to try using the Aegis
databinding which works quite well with them. I'll see if I can churn out a
test case though for this and see what might be wrong.

The plot thickens. I changed the code back, so that Collection was no
longer there, and the orginal ArrayList is there. The code is *still*
crashing however. My input has not changed -- it is hard-coded, so I
know for a fact it has not changed. I am now suspecting some new
resource that may have been posted to an online maven repository,
because that's the only thing I can think of that could have injected
new code into my code-base, as I am building with maven. Is anyone aware
of any new CXF artifact or dependency that has hit public maven
repositories within the last day?
Thanks,
Brad
