orgbouncycastleasn1DLApplicationSpecific cannot be cast to orgbouncycastleasn1ASN1Sequence

This error occurs when you try to cast an instance of the DLApplicationSpecific class to an instance of the ASN1Sequence class. This is not possible because the two classes are not related.

To fix this error, make sure that you are using the correct class when casting objects. Check the documentation for the classes you are using to ensure that you are using the correct method for casting objects.

You may also need to modify your code to handle different types of objects. For example, you could use an instanceof operator to check the type of an object before casting it to a specific class
