SQL DEV DIFF TOOL : OMITS OBJECT IDENTIFIER CLAUSE

Question

Hi,
The following is encountered in SQLDeveloper 3.2.20.09 where using Tools > Database Diff... results in DDL that omits the "OBJECT IDENTIFIER IS PRIMARY KEY" clause.
Test SQL:
create type dummy_typ as object
  id_num    integer,
  other_num integer
create table dummy_otbl of dummy_typ
  constraint dummy_otbl_pk primary key ( id_num ) using index
  object identifier is primary key;
When the diff tool generates the create table script it creates it but omits the OBJECT IDENTIFIER IS PRIMARY KEY clause. 
Example:
  CREATE TABLE "AIMS_FEATURES"."DUMMY_OTBL" OF "AIMS_FEATURES"."DUMMY_TYP"
  ( CONSTRAINT "DUMMY_OTBL_PK" PRIMARY KEY ("ID_NUM") ENABLE
Is this a Bug of sorts? Thanks in advance for your responses
Cheers,
Anand

Possibly.
What's the DDL for the object you're comparing it to, or is it just 'missing?'
I'm looking at the DDL generated for the object in the object editor and it's including the phrase so the DIFF should also pick that up.
  CREATE TABLE "HR"."DUMMY_OTBL" OF "HR"."DUMMY_TYP"
   ( CONSTRAINT "DUMMY_OTBL_PK" PRIMARY KEY ("ID_NUM")
  USING INDEX (CREATE UNIQUE INDEX "HR"."DUMMY_OTBL_PK" ON "HR"."DUMMY_OTBL" ("ID_NUM")
