Symptom
A data import or export task fails, and the following exception is thrown in the task summary: javax.crypto.BadPaddingException: Given final block not properly padded.
Possible causes
This exception is caused because the ODP password failed to be decrypted.
Solutions
Solution 1
We recommend that you install Open JDK 1.8.0_242 or later to ensure consistent versions of JRE and JCE.
Solution 2
Download the jce_policy plug-in of the same version as the JDK being used from the Oracle official website, decompress the package, and then replace the original local_policy.jar and US_export_policy.jar files with those in the decompressed files.
Solution 3
Upgrade ODC to V2.3.0 or a later version. This issue will not occur in ODC V2.3.0 and later versions because the decryption policy is changed.
