I found wrapping the BinaryResponseWrite with a try/catch solved the
problem and allows null values to be returned.
BinaryResponseWriter.java:141
try {
val = useFieldObjects ? ft.toObject(f) : ft.toExternal(f);
} catch (NumberFormatException e) {
val = null;
}
It seems only the BinaryResponseWriter is actually that fussy about
null items. Once it comes back to the client for display, it is
handled without error.
