Using basic 256 (rsa oaep), encrypting data with SunJCE provider and decrypting the encrypted data with
Bouncy Castle lightweight crypto API (non-jce provider) produces the following exception:

Should check if there is something to do about this or is it just an "unsupported feature" of the Sun JCE implementation.

Closing the issue as per #164 it has been deprecated and moved away from the main stack part (did never work properly in all cases and additionally cannot be used anyway in modern java versions).
