From the adwork001.log ,Have you tried to check line 105 in the script and see if it gives any clue?
sqlplus -s APPS/***** @/&un_ja &batchsize 3 u03/oracle/CRP1PROD/apps/apps_st/appl/ja/12.0.0/patch/11
ERROR at line 1:
ORA-01722: invalid number
ORA-06512: at line 105
Could not find much in internet.The only hit I have found in (Bug 7120055 : FAILED: FILE JAIRGMSETUPMIG.SQL ON WORKER 1) but it does not tell much, so you may need to log a SR and get more details about this bug.
