Drive-by comment: If the exception creation is the problem, maybe we should turn it stackless (overriding the `fillInStackTrace` in the subclass of `BadPaddingException`), assuming this exception does not leak out of the method to the users and/or users do not require the stack trace. This would not put us into security-related discussion whether moving the exception on conditional path improves the fidelity of timing. ------------- PR Comment: https://git.openjdk.org/jdk/pull/12732#issuecomment-1484745045
