I was finally able to reproduce this in a unit test. It looks like one of
the geoprocessing routines I created, is adding a LinearRing that has no
coordinates. So when I serialize the feature to GML for transport, I have a
LinearRing section that looks like this:
<gml:innerBoundaryIs>
<gml:LinearRing>
<gml:coordinates xmlns:gml="http://www.opengis.net/gml";
decimal="." cs="," ts=" "/>
</gml:LinearRing>
</gml:innerBoundaryIs>
It looks like Xerces will treat the content of coordinates as a String,
because there are no coordinates.
I'm looking into what dependency is causing this behavior in case you are
interested.
