Glad you found something
I added a comment to
http://www-01.ibm.com/support/knowledgecenter/ssw_ibm_i_72/rzaki/rzakiautostrjrnl.htm?lang=en
requesting clarification as to when one should use the data area QDFTJRN 
and when one should use the command STRJRNLIB.
From what I remember QDFTJRN came out first and was deprecated by 
STRJRNLIB.
However, Look at this:
crtlib robdelme 
Library ROBDELME created. 
CRTJRNRCV JRNRCV(ROBDELME/JRNRCV0001) 
Journal receiver JRNRCV0001 created in library ROBDELME.
CRTJRN JRN(ROBDELME/JRNRCV) JRNRCV(ROBDELME/JRNRCV0001) 
Journal JRNRCV created in library ROBDELME. 
CRTDTAARA DTAARA(robdelme/QDFTJRN) TYPE(*CHAR) LEN(80) 
Data area QDFTJRN created in library ROBDELME. 
CHGDTAARA DTAARA(robdelme/QDFTJRN (1 10)) VALUE(robdelme)
crtjrnrcv robdelme/x0001
Journal receiver X0001 created in library ROBDELME. 
CRTJRN JRN(ROBDELME/X) JRNRCV(ROBDELME/X0001) 
Journal X created in library ROBDELME. 
CHGDTAARA DTAARA(robdelme/QDFTJRN (11 10)) VALUE(x) 
CHGDTAARA DTAARA(OVERRIDE/QDFTJRN (21 10)) VALUE(*ALL) 
Library OVERRIDE not found for data area QDFTJRN. 
CHGDTAARA DTAARA(robdelme/QDFTJRN (21 10)) VALUE(*ALL) 
CHGDTAARA DTAARA(robdelme/QDFTJRN (51 10)) VALUE(*ALLOPR) 
crtpf robdelme/huh rcdlen(80) 
File HUH created in library ROBDELME. 
Member HUH added to file HUH in ROBDELME. 
dspfd robdelme/huh 
File is currently journaled . . . . . . . . :            Yes 
Current or last journal . . . . . . . . . . :            X 
  Library . . . . . . . . . . . . . . . . . :            ROBDELME
dsplibd robdelme
Journaling information: 
  Currently journaled  . . . . . . . . :   YES 
  Current or last journal  . . . . . . :   JRNRCV 
    Library  . . . . . . . . . . . . . :     ROBDELME 
  Journal images . . . . . . . . . . . :   *AFTER 
  Omit journal entry . . . . . . . . . :   *NONE 
  New objects inherit journaling . . . :   *YES 
  Inherit rules overridden . . . . . . :   YES 
  Journaling last started date/time  . :   10/14/15  11:51:33
STRSQL
CREATE TABLE ROBDELME.DELETETHIS (MYCHAR CHAR (5 ) NOT NULL WITH
DEFAULT) 
Table DELETETHIS created in ROBDELME. 
File is currently journaled . . . . . . . . :            Yes 
Current or last journal . . . . . . . . . . :            X 
  Library . . . . . . . . . . . . . . . . . :            ROBDELME
Apparently the data area takes precedence, irregardless of whether the 
table was created with CRTPF or CREATE TABLE.
(Testing done on 7.2 machine at cume 5135, TR2 and DB2 group 8.)
