Solution :

As per the Oracle Doc : Autoconfig fails when running Adgentns.Pl with ERROR: apps/bin/jre and apps/bin/java not found [ID 731685.1], We performed the following,

Replace current adgentns.pl by adgentns.pl version120.4.12000000.3

1.1 Download patch 7207440 TXK - 12.0.4 Consolidated Patch 1 from Metalink
Do not apply it
1.2 Extract the file adgentns.pl 120.4.12000000.3 from patch 7207440
1.3 Backup your current adgentns.pl
1.4 Replace your current file by this file adgentns.pl 120.4.12000000.3
1.5 Retest autoconfig.

Finally it fixed our issue.

Thanks.
