R12.2.2:OAF page error while using third party signed jars

Hi All,

I am getting below error while using third party signed jar file in custom OA page in R12.2.2. All the custom OA pages are located in $JAVA_TOP/<xxx> folder and I ran adcgnjar to generate customall.jar file. I have exploded bouncycastle jar file to $JAVA_TOP/org/. The same setup is working in R12.1.3 but in R12.2.2 its not working and ending in below error.

All the steps mentioned in note: Developing and Deploying Customizations in Oracle E-Business Suite Release 12.2 (Doc ID 1577661.1) has been followed. Please suggest how to invoke third party signed jar files in custom OA page in R12.2.2
