adcgnjar error out in patch environment

We are using EBS version 12.2.4

We are trying to make fs1 and fs2 environment in sync. So every time when developer develop code, we have them modify both fs1 and fs2 environment. When try to generate the customall.jar file using adcgnjar, it is working fine when running it in the run environment. But when try to run this in the patch environment, it is given password wrong error. But I know I am using the same password. What am I missing? Why is the same utility works ok in run environment but not patch environment? Gurus, please advise. Thank you.
