[Pljava-dev] ResultSet is read-only error for Trigger?

I'm trying to do a very simple trigger before moving onto the complex
stuff that I need pljava for.

My Java code is extremely simple:
public static void ProvisionOrder2(TriggerData td) throws
SQLException {

ResultSet _new = td.getNew();
_new.updateBoolean("provisioningcomplete",true);
}

My trigger setup is likewise pretty simple:
CREATE OR REPLACE FUNCTION provisionorder()
RETURNS "trigger" AS

'com.prodeasystems.rsc.prvstester.Provisioning.ProvisionOrder2'
LANGUAGE 'java' VOLATILE;
ALTER FUNCTION provisionorder() OWNER TO postgres;

CREATE TRIGGER provisionorder_trigger
AFTER UPDATE
ON serviceproviderprovisioned
FOR EACH ROW
EXECUTE PROCEDURE provisionorder();

When I update my row, I see the following error:
provision=# update serviceproviderprovisioned set
readytoprovision='true' where rhcjid='x';
ERROR: org.postgresql.pljava.jdbc.UnsupportedFeatureException: Feature
not supported: ResultSet is read-only

The example provided in the users guide
(http://wiki.tada.se/display/pljava/Triggers) implies that the
ResultSets can be manipulated. Why am I seeing this error?
