I tried changing it to be the last field, per your recommendation, but
alas, it did nothing. I both tried changing the order of the
attributes, and putting the accessor methods last (was first).
P.S. This was using Glassfish 2.1.1. I used to be able to deploy and
work in Glassfish 3.1.1, but GF 3 now fails on writing the WADL to the
outputstream with "WebappClassLoader unable to load resource
[java.util.TreeSet], because it has not yet been started, or was
already stopped". Any idea if this bug is of a recent date?
