Hmmm... hard to say since the class changed a bit and current version
has a comment at line 762, but anyways, looking at the first lines
of the createSchema method:
CoordinateReferenceSystem cs =
featureType.getDefaultGeometry().getCoordinateSystem();
long temp = System.currentTimeMillis();
if (isLocal()) {
Class geomType = featureType.getDefaultGeometry().getType();
it's either that the feature type is null, or that the feature type has
no default geometry. Why this is happening, I don't know.
Cheers
