Cannot Invoke Procedure - Privileges Error

Hi,

I am experiencing an issue with version 2.2.9 of HSQLDB when attempting 
to invoke a procedure.  I create the procedure using the following DDL 
script:

/*u0*/CREATE SCHEMA "udm_fgac" authorization dba;
SET DATABASE DEFAULT INITIAL SCHEMA "udm_fgac";
SET SCHEMA "udm_fgac";
CREATE table "udm_fgac"."living_user_external_credential_view" ( 
"living_user_external_credential_id"     INTEGER        PRIMARY KEY,
	"living_user_id"             INTEGER        NOT NULL,
	"customer_id"                varchar(255)  NOT NULL,
	"customer_number"            varchar(255)  NOT NULL,
	"company_id"                 INTEGER           NOT NULL
);
GRANT ALL ON "udm_fgac"."living_user_external_credential_view" TO 
PUBLIC;

CREATE PROCEDURE "udm_fgac"."get_living_user_id" (IN 
"p_identity_provider" varchar(255),
IN "p_identity_provider_id"         varchar(255),
IN "p_pin"                			 varchar(255),
OUT "living_user_id"				bigint
)
READS SQL DATA
    SELECT 1 INTO "living_user_id" FROM 
"udm_fgac"."living_user_external_credential_view";
.;

GRANT ALL ON ROUTINE "udm_fgac"."get_living_user_id" TO PUBLIC;

The script executes correctly but when I try and call the procedure 
using the following command:

call "udm_fgac"."get_living_user_id"(?,?,?)

I get the following error:

Caused by: java.sql.SQLSyntaxErrorException: user lacks privilege or 
object not found
	at org.hsqldb.jdbc.Util.sqlException(Unknown Source)
	at org.hsqldb.jdbc.Util.sqlException(Unknown Source)

Can you help with this as its driving me mad!

Thanks

Simon
