java.io.IOException: org.bouncycastle.jcajce.provider.BaseSingleBlockCipher$BadBlockException: unable to decrypt block

This error message is normal and is expected in case of importing any content which contains password like process or dataset
You could ignore this as it won't impact the PAM functionality.
